Decide how you need it to behave: spread (toast/dips) or melt (warm topping/baking).
Pick the closest option from the table: 1:1 swaps for the easiest texture match.
Use the listed ratio, then adjust consistency: if it’s too thick, stir in a small splash of milk; if too thin, chill 10 minutes.
Taste and fine-tune: add salt for stronger “cheesy” flavor or a tiny lemon splash for sharper tang.
For baking, let the substitute warm into the dish for 1–2 minutes before spreading/adding texture-heavy elements.
