Good tomatoes too; large, easy to remove seeds, and most have good flavor. I generally grow one oxheart variety each year. Hungarian Heart is one of the most productive tomatoes I've grown, and many swear by it. I can substitute oxhearts for paste tomatoes when making canned salsa, the prep goes quickly due to their large size (most are 8 oz. or more) and the results flavorwise are very good... but they are a little juicier than the paste types,
@seedcorn , so probably not what you are looking for. When using oxhearts for canned salsa, I ladle off the excess juice until I get the consistency I want.
But for the most part, I prefer to use oxhearts fresh, especially chopped for tacos or salads. Their mild, sweet flavor is well suited to fresh use. They make a great sauce too, but it takes awhile to cook down.
