I once had a delicious red sauce that was made with nothing but tomatoes and fresh basil, cooked down to a sauce. After raiding our garden, I had plenty of tomatoes and fresh basil to try this sauce. After piecing the tomatoes, I pulled out some of the juice, added plenty of finely-diced basil and put it in my large roaster on the lowest setting to cook down. It took about 3-1/2 hours. Can't wait to use this over pasta or in seafood dishes.
