Can I use canned tomatoes instead of fresh cherry tomatoes?
Yes, but the sauce will be less bright. Use one 14-oz can of diced tomatoes plus their juice, and reduce the cooking time by 5–10 minutes since canned tomatoes break down faster.
What if I don't have Pinot Grigio?
Any dry white wine works; substitute vermentino, sauvignon blanc, or pinot grigio in the same amount. Avoid oaky wines. Skip wine entirely and add 2 tbsp chicken broth if you prefer.
How do I know when the sauce is done?
The cherry tomatoes should be soft and beginning to collapse, the sauce should coat the back of a spoon, and flavors should taste balanced—about 20–30 minutes of simmering after adding tomatoes.
Can I make this ahead?
Yes. Refrigerate the finished sauce up to 3 days, or freeze up to 2 months. Reheat gently on the stovetop over medium-low heat, adding a splash of water if it's too thick.
How do I scale this recipe?
Double or halve all ingredients proportionally. If doubling, increase simmering time by 5–10 minutes to allow flavors to meld and tomatoes to soften fully.
