Keep these guidelines in mind:
Don't buy seasoned or "stewed" tomatoes with herbs and vegetables
added; they're less versatile. Who wants basil in guacamole?
Instead, buy plain tomatoes and season with fresh herbs.
Cook canned tomatoes thoroughly when you're making a sauce. Even
though they are precooked, simmering for 10 minutes brings out
their natural sweetness and rids them of acidity.
On average, a 28-ounce can of whole tomatoes contains 15 tomatoes
and 11 ounces of liquid. Use the juice, especially if you've
splurged on high-quality tomatoes. It's full of flavor.
