I cut the original recipe in half because it made a ton, and I also made some adjustments, specifically to the quantities of garlic and lime juice. Feel free to omit the garlic altogether and start out conservative with the lime juice since some limes are juicier than others. Try the juice of one lime to start and then you can always add more. Also, the cookbook calls for "tomato sauce," which does not mean marinara or spaghetti sauce. It's referring to cans of tomato puree with a small amount of seasoning, like this from Contadina. I didn't have that on hand so I used Pomi tomato puree. But you can also use fresh, seeded tomato that's been chopped finely or pulsed in the food processor.
