I built this recipe scaling app after testing how small changes affect recipes. When you change serving sizes, I adjust ingredient amounts with rules for items like baking powder, yeast, and seasonings because they often need different treatment than flour or liquids. You get cleaner results without losing the intended texture or flavor. The app formats recipes into a clear layout, merges duplicate ingredients, and helps you edit recipes faster.
I built the core architecture for the Recipe Scaler using JavaScript modules. Linear multiplication breaks baking chemistry for reactive ingredients like yeast and leaveners, so I implemented a dampened scaling formula to keep larger batches consistent. I hit browser security limits when trying to fetch recipe links directly, so I added a raw text parser fallback to read numbers and fractions. The parser struggles with non-standard lines like “juice of 1 lemon,” and a negative serving size bug currently bypasses validation. I also built a normalization pipeline to merge duplicate ingredients, though keystrokes currently drop cursor focus due to full page re-renders. My next update will focus on fixing the parser and improving editing stability.
Thank you for following along with the development process.
