Recipe Nutrition

Energy and macronutrients added up from the packets you have.

It runs entirely in this browser tab: nothing you type is uploaded, and every figure it gives says whether it is arithmetic or a rule of thumb.

What it takes

One ingredient on each line: the name first, then the weight in the recipe and the energy, protein, carbohydrate and fat off the packet. The last three may be left out.

An example

oats 100 379 13 68 7
milk 250 64 3.4 5 3.6
banana 120 89 1.1 23 0.3
peanut butter 30 588 25 20 50

Questions

Is my recipe uploaded anywhere?
No. The whole application is carried as WebAssembly and runs on your own device. There is no server to send anything to, and none of these tools makes a network request while it works.
Why does it ask me for the calories instead of knowing them?
Because a food table large enough to be useful is larger than this whole application, goes out of date, and differs by country and by brand. The figures on the packet in front of you describe what you are actually cooking; a table would describe something like it.
Is the cooking time safe?
It is a starting point. Roasting times depend on the shape of the joint, how cold it went in and how honest the oven is, and none of those is a number this tool has. The safe internal temperature is printed beside every time for exactly that reason: a thermometer decides, and the clock only says when to check.
Why do some of the tools refuse a number I asked for?
Because the answer would have been unsafe or meaningless. The fermentation tool will not go below the salt concentration the published guidance sets, and the tools that divide by a portion refuse a portion of nothing rather than printing an infinity.
