Show HN: I Derived a Pancake
89 points by bkazez 3 days ago | 28 comments
After 25 years of making other people's pancake recipes - always yearning for more tang, more fluff, and more predictability - I decided to derive the pancake recipe from the chemistry.

You mark checkboxes for what you have on hand (ricotta, sour cream, kefir, buttermilk, yogurt, cottage cheese, lemon, cream of tartar, etc.) and it computes the best recipe based on targets for acid, fat, salt, sugar, and CO2.

My particular favorite are the yeast-raised lemon ricotta kefir pancakes - the best I've ever had.

The math is done in a small pure-ESM library: ingredient composition to component masses and acid moles, a stoichiometry layer, and a bisection solver for the target deficits.

I'm not a chemist, so if something is off, tell me and I will fix it!

A ten hour wait doesn't really strike me as a pancake? You should have a "it's 730am, there's four screaming girls, only two of which are related to me, the dogs are begging for scraps, and the demand for pancakes has crossed into Veblen goods territory."

The default has the 'tang' slider at maximally tangy, which is where the yeast and wait come in. If you back off on that the recipe looks more like the standard quickbread I'm used to.

The yeast and ferment is going to make it more acidic, and more tender because the gluten will be weakened. I imagine you could use cake flour instead and get close to the same tenderness, but the flavor would be different.

The good thing about that scenario is no matter how the pancakes come out, you've already won

One size doesn't fit all. By your logic, homemade sourdough isn't bread, you should have packaged Wonder bread.

Keep a box of Krusteaz in the pantry for the kid sleepovers, prepare the night before for an adult brunch.

It depends. The inspiration sometimes comes after a Saturday evening with friends and lots of drinks. Having a foolproof recipe comes in handy, and having the perfect stress-free pancake batter already made the next morning turns you into a household hero.

If you know the kids are going to want pancakes in the morning you just prepare it at night? You can ask them to confirm over dinner...

While I can confirm sourdough pancakes are quite nice, I am satisfied with Krusteaze :)

Well I have a new favorite website. I don’t know the last time that I read something that was so thoroughly and multidimensionally my shit.

Not actually measuring crispness when you self report having the perfect equipment to do so is a cruel, cruel tease though.

Awesome work. I'm really interested in the parametric-driven recipe card. I wanted to do something like this for bread recipes where you can tweak the hydration / salt levels to alter the recipe but still get a traditional recipe card. I would be really curious to hear about the approach in more detail.

Yes! The world needs more Parametric-driven recipes. This is fantastic. Love it.

This is awesome, chefsteps should hire you to do their parametric recipes.

You've covered dairy and acid ingredients, but I honestly have no idea what "Unrendered Berkshire pork fat" is or where I would get it. Is that bacon grease? Saltpork? Lard is common but rendered.

Probably suet, which is raw and found around kidneys and loins.

I would love to see the gluten and dairy free pancake recipe incorporated into this one for additional customizability. For example, what if I’m gluten free but not dairy free? Or happen to only have soy milk on the day but I’ve got plenty of butter?

As a lemon ricotta pancake and yeast enthusiast, I look forward to trying your recipe! Thanks for sharing!

Protip: you don't need buttermilk, you need milk and acid. 1 cup milk and 1tbsp vinegar do the same job and are already in your kitchen.

I will do yeast-raised waffles but usually don't bother with pancakes. I usually don't have buttermilk so I mix yogurt and milk. I just eyeball it, about 1/4-1/3 yogurt makes a good consistency. While food science is fun, there's no way I'm doing that much work on a Saturday morning.

> the use of imprecise cup measurements rather than weights

It really does not matter. Both because variation doesn't matter and because weights vs volumes are not going to give a big enough variation to really be detectable.

It doesn't matter for small items like salt or baking soda, but you can get pretty different results scooping flour depending on how compressed the flour storage is, and how much the scooping packs down that flour.

There's a reason that every bakery measures by weight. If you value consistency, and recipes should be consistent, you go by weight. You can say it doesn't matter, and in some cases it might not, but the entire baking industry doesn't agree with your statement.

Flour is always the canonical example and I flat out reject it. It's not true. If you think it's true, you've convinced yourself it's true to avoid addressing other problems in process you have.

Here's a thing: a given measure of flour (by any means, volume or weight), a single one kept in a cupboard, not remeasured, is going to have a different weight on different days that have different ambient humidity levels.

The tools of the kitchen are imprecise. The environment is not well controlled. And human taste is robust against micro variations.

A given weight of flour will have a different weight on a different day?

As it absorbs more or less moisture from the air due to ambient humidity changes, yes. The same reason your wooden furniture will also significantly change in dimensions such that there's no point in being more than 1/16th of an inch precise in your measurements; your design and construction technique is far more important.

It certainly can matter for proper baking (which this recipe seems to be?), though for traditional pancakes I would never bother. But there's a reason that bakeries weigh their ingredients. It's more consistent and allows for different people to get more similar results.

The baking industry isn't really measuring by weight, they are measuring by bag, which happens to be delineated in weight.

Look, this is arm chair, YouTube cooking. There is so much variation in recipes that 10% here and there is not going to make or break any recipe.

There is zero ability to make a "universally better" version of a recipe by micro optimizing ingredients. For one thing, you can't easily control temperature and humidity variations on your environment. If people think 2% difference in flour content is going to make or break their bread recipe, then daily humidity variations will definitely have an impact. But it doesn't, really. It's the sort of thing people blame when they don't have good process or good technique.

For another thing, there is no way to evaluate the outcome as "better". Better for you, perhaps, but even then, it's mostly psychosomatic. I've doubled the amount of baking soda in a recipe before and it has had zero impact. I've never measured flour by weight and my cookies come out exactly the same as my wife's when she breaks out the microscale

I've been cooking for a long time. I have family members who refuse to come to Easter Dinner unless I'm the one cooking. I barely measure anything, ever. Even when I'm baking. It matters to have things in the right ballpark, but 5% variations don't matter.
