San Marzano vs Roma VF for sauce

Compare San Marzano and Roma VF, two paste tomato choices, and learn what matters when cooking fresh tomato sauce.

By ShopTomato · Variety research and serving ideas

Start with flesh and moisture

Both belong in a sauce tomato comparison. San Marzano is an elongated paste type with several strains. Roma VF produces small plum-shaped fruit with a high solids-to-juice ratio. Neither name guarantees the same result from every grower or harvest.

Choose for the cooking you want to do

Dense fruit is a practical starting point for a thick sauce. Cut a sample tomato and look at how much flesh and free juice it contains. A juicier batch can still make sauce; it may simply need more reduction. Taste before adding sugar or extra acid.

Compare batches, not reputations

Cook equal weights in similar pans with the same seasoning and compare the finished consistency. A named variety is useful information, but ripeness and the actual batch also matter.
