Recipes should be written with the quantities in the procedure. So instead of reading

Mix flour, salt and sugar in a large mixing bowl

It should be

Mix flour (300g), salt (1/4 tsp), and sugar (20g) in a large mixing bowl

That way you don’t need to read/refer to ingredient list, read/refer to ingredient list, etc

All solids should be listed by weight.

All liquids should be listed by volume.

SI units only. (Grams for solids, mL for liquids)

More graduated cylinders and volumetric flasks in the kitchen please.

If you’re asking scientists about writing protocols, you clearly don’t know how scientific protocols work. If anything, scientists need to take lessons from recipe writers on how to write protocols. Scientific protocols are notoriously difficult to replicate.

Here’s a burger recipe written like a scientific methodology:

Raw beef patties (Carshire Butcher) were prepared on a grill (Grillman) according to manufacturer’s instructions. The burger was assembled with the prepared patties, burger bun (Lee Bakery), lettuce (Jordan Farms), American cheese (Cairn Dairy), and various toppings as necessary. Condiments were used where appropriate. Assembled burgers were served within 15 minutes of completion.

I’ve been cooking at home, and occasionally in restaurants, since I was about ten or so. So, 40ish years.

No single standard is better than the others. It does suck that there isn’t a single one that is used as a base, and then gets converted by the cook into their preferred units and structure, but even that has issues.

The good news is that most cooking, and even most baking, is very forgiving of the kind of discrepancies between sizes of lemons, onions, etc. You don’t really run into trouble until you’re dealing with things that react chemically based on the ratio of ingredients, which is still most common in baking, and not even all baking.

Even in those types of recipes, it’s usually flour that’s the problem, not leaveners, since flour compacts readily and to a high degree. But, then again, most modern recipes like that are going to be in weight measures, or in baker’s ratios. You’d be using a scale for the fiddly recipes.

So, generally, just guesstimate your produce size the first time you make something. It’s not going to be so far off that the results will suck if the dish itself doesn’t. Then you tweak things until it fits what you prefer, which is what happens anyway as you build your recipe book/collection.

My old recipe book had scribbled notes in the margins from years of refinements. When I copied that into a digital recipe manager, I added them in directly. Now, I’m able to just enter the original recipe, then add my notes as parentheticals or whatever as I refine.

Even with those detailed notes, a given recipe won’t always be reproducible as exactly the same. That’s because you just can’t standardize everything. You use good produce, there’s going to be varying water content, slight differences in flavor compounds, more or less sugars, so to get the same results over time, the cook has to know how to adjust for those things on the fly.

Of equal import is that no matter how scientific your process of recipe development is, the table is never the same as the cook. My taste buds and brain aren’t the same as my wife’s, my kid’s, my cousin’s, etc. So there’s limits to the benefits of standardized recipes on the plate.

Now, formatting? That’s a huge help.

You want your ingredient list to include instructions about when an ingredient is used in multiple places. You want lists broken down in sections when a recipe calls for multiple procedures (like making the main dish, a sauce, and a crust).

In the instructions, make sure the ingredient quantities are included for redundancy.

If there’s an instruction about duration that’s variable explain what the variables change. As in: bake for 10 to 15 minutes. Okay, great. What’s the difference? If my stove runs hot and I go for the short time, will I see golden brown, and will 15 be burnt or just really dark? Yeah, you can’t expect identical results from one circumstance to the next, but at least drop an “until golden brown” at the very minimum.

That applies to any variable, imo, but it can get to be too much detail in complicated recipe.

Cooking and baking are chemistry, physics. But they’re also an art. The more you try to strip a recipe of flexibility, the less successful it’s going to be for the next cook.

OP right now

This would only make sense, if all people were baking with the exact same ingredients, in the exact same environment, with the exact same equipment. You know, like in a factory.

For households and the like, it makes sense to have a bit of variation, until you find the way that makes it perfect for you.

Autist and scientist here: you’re thinking of baking. Baking is the science one, cooking is infuriating because all of those really vague and inaccurate instructions are in fact as precise and accurate as they need to be. Seasoning is done with the heart, you do have to stir or knead u ntil it “looks right”, “a handful” is the right amount to add. The only way to find the “right” amounts is to cook over and over until you instinctively know what enough looks like.

Anyway the ingredient I really really hate is from Jamie Oliver’s “working girl’s” pasta, where he lists “2 big handfuls of really ripe tomatoes”. I HAVE CANNED TOMATOES YOURE GETTING CANNED TOMATOES JAMIE, I DONT HAVE FUCKING TIME TO GO LOOKONG FOR REALKY RIPE TOMATOES

Also standard teaspoon is 5ml. Just use that and taste to see if it needs more.

Cooking is not a standardized or reproducible process at home, because the variables outside of anybody’s control. Modern mass recipes give only the illusion of being reproducible algorithms, but they will never achieve that.

Grappling with the complexity of different tooling, supply chains, seasonality and so on, all within a recipe, is a futile effort. That complexity must be handled outside the recipe.

You should check out the super old website called “cooking for engineers”.

I’m an American biochemist, I also never learned the english system because my school transitioned to metric too fast. The mental burden of trying to cook using english units after working all day in the lab using that same part of my brain leads me to just not want to cook 95% of the time. But when I do cook I have optimized processes for my few simple recipes. When I bake I usually use a metric recipe or convert a English one, and optimize it before making a large batch of something.

I think a major one is to try to avoid trusting in unfounded precision.

If you want to make lemonade like a chemist, you don’t just weigh out some lemon juice and add it to water and sugar. You measure sugar and citric acid content of the batch of lemon juice, then calculate how much water will dilute it to the right pH, and how much sugar will bring it to your desired osmolarity. In reality, no one is going to do that unless they run a business and need a completely repeatable. If you get lazy and just weigh out the same mass of stuff with a new batch of lemon juice, you could be way off. Better to just make it and taste it then adjust. Fruits, vegetables, and meats are not consistent products, so you can’t treat them as such.

If i were to be writing recipes for cooking, I would have fruits/vegetables/meats/eggs listed by quantity, not mass (e.g., 1 onion, 1 egg), but i would include a rough mass to account for regional variations in size (maybe your carrots are twice the size of mine). Spices i would not give amounts for because they are always to taste. At most, I would give ratios (e.g. 50% thyme, 25% oregano). Lots of people have old, preground spices, so they will need to use much more than someone using whole spices freshly ground. I think salt could be given as a percentage of total mass of other ingredients, but desired salinity is a wide range, so i would have to aim low and let people adjust upward.

Baking is a little different, and I really like cookbooks that use bakers percentages, however, they don’t work well for ingredients like egg that I would want to use in discrete increments. For anything with flour, I would specify brand and/or protein level. A European trying to follow an American bread recipe will likely end up disappointed because European flour usually has lower protein (growing conditions are different), which will result in different outcomes.

I will say in defense of teaspoons, most home cooks have scales that have a 1 gram resolution, though accuracy is questionable if you are only measuring a few grams or less. Teaspoons (and their smaller fractions) are going to be more accurate for those ingredients. Personally, I just have a second, smaller scale with greater resolution.

Not a scientist, but an easy improvement would be to use weight instead of volume for most measurements. “A cup of flour” can vary greatly depending on how compressed/dense it is.

At some point, food blogs stopped being about food and became personal memoirs with a side of seasoning. It probably started innocently enough—people sharing family recipes, adding a little background, a photo or two. But then came the SEO optimization, the Google gods demanding 1,500 words per post, and suddenly, every recipe for scrambled eggs begins with a story about someone’s childhood summer in Tuscany and how their Nonna taught them the sacred art of cracking an egg with one hand.

Now it’s standard: you search “how to make pancakes” and end up reading about a foggy morning in 2003, a breakup, a golden retriever named Milo, and how cooking became therapy. You scroll and scroll, dodging ads, autoplaying videos, and a pop-up asking you to “join the culinary journey.” Somewhere, buried like treasure, is the actual recipe—five steps long, could’ve fit on a Post-it note.

And yes, this is exactly that. This is the bloated preamble you didn’t ask for. You came here for temperatures and timings, and instead, you got this paragraph complaining about the very thing it’s doing. You’re now part of the cycle—scrolling, sighing, wondering when we collectively decided that roasting vegetables required a narrative arc.

Anyway, here’s the recipe. Probably. Keep scrolling.

American here: can we please have measurements by mass not by volume and metric units. It would make repeatability so much easier.

Not any kind of scientist, but an adventurous home cook

I’d really like the USDA/FDA/etc. (maybe not under the current administration) to publish sort of a food safety handbook full of tables and charts for stuff like canning, curing meats, cooking temps, etc. targeted to people like me.

I’ve recently been experimenting with curing meats, I’ve done bacon, Montreal style smoked meat, corned beef, Canadian bacon, and kielbasa.

And holy fuck, is it hard to find good, solid, well-sourced information about how to do that safely.

And I know that information is out there somewhere, because people aren’t dropping dead left and right of listeria, botulism, nitrate poisoning, etc. because they ate some grocery store bacon.

I just want some official reference I can look at to tell me that for a given weight of meat, a dry cure should be between X and Y percent salt, and between A and B percent of Prague powder #1, and that it needs to cure for Z days per inch of thickness, and if it’s a wet brine then it should be C gallons of water and…

When I go looking for that information either I find a bunch of people on BBQ forums who seem to be pulling numbers out of their ass, random recipe sites and cooking blogs that for all I know may be AI slop, or I find some USDA document written in legalese that will say something like 7lbs of sodium nitrite in a 100 gallon pickle solution for 100lbs of meat, which is far bigger than anything I’ll ever work with, and also doesn’t scale directly to the ingredients I have readily available because I’m not starting with pure sodium nitrite but Prague powder which is only 6.25% sodium nitrite.
