With almost everything, one wonders how to substitute something canned for something fresh. But with tomatoes, the question is reversed; almost every recipe I’ve seen in a cookbook or online that deals with tomatoes will almost always referred to the canned version. And since tomato product cans always use an epoxy lining that contains BPA, that may bother one.

It took a while to find this advice, thus I’m blogging it for the future. I got it from cookingclub.com, almost randomly:

Can fresh diced tomatoes be substituted for canned ones?

Yes. To substitute fresh diced tomatoes for a 14.5-ounce can of undrained diced tomatoes, use approximately 1 1/4 cups of diced fresh tomatoes and 1 cup of liquid. If your recipe calls for a 28-ounce can of undrained diced tomatoes, use about 2 1/2 cups of diced fresh tomatoes and 1 cup of liquid. Use any liquid that seems appropriate for your recipe, such as water, broth or tomato juice.

And now I think I can make some stew and curry in peace.
