Get a bunch of tomatos (I prefer the Better Boys if you can find them), slice in quarters and blend in blender. Add olive oil, basil, a clove fresh garlic run through a galic press and blend again. Once it's fully blended add salt, a small amount worchester sauce and some water to bring it to the consistency you want. Add the water slowly blending and tasting between each addition.
Add a little pepper-flavored vodka and you'd have yourself a hell of a bloody mary.
