Over the holidays, I created a chrome extension that allows a user to dynamically adjust the number of servings for a recipe they are preparing. The extension works for recipes on halfbakedharvest.com
The extension will scale ingredient amounts in the browser, based on the selected number of servings.
Scaling recipes has always been annoying to me… if I try to do it by hand or in my head, I will either not scale by the correct factors or I will forget to scale an ingredient while checking back with the recipe.
The recipe-scaler removes this point of friction, so you can focus on cooking instead of on (surprisingly tricky) math.
You can check out a live demo of the scaler in action here: www.bambielli.com/recipe-scaler/
