Decide how you’re using toma cheese: melting (pizza/bake) vs. slicing (snacks/sandwiches).
Use the ratio in the table: start with 1:1 for mild melters, or use ¾:1 for sharper swaps like mild cheddar.
If the substitute tastes flatter than toma, add tang in small steps (a pinch of lemon juice or a tiny splash of vinegar).
For better melt, grate the cheese or slice thin; for less melt, keep it thicker slices.
Taste and adjust salt: some substitutes (like cheddar) bring extra saltiness; others (like mozzarella) may need a pinch more seasoning.
