Substitutions are conditional; this is how the site handles that.

Each page opens with the single best substitute and the exact amount, so you can act in ten seconds.

A ranked table of everything that works, marked as a straight swap, a swap that needs a tweak, or one you will taste.

What the ingredient is doing in your recipe decides the swap. Where it matters, the page asks.
