Slice the oranges
down the middle and squeeze the juice. Mash
a head of garlic in a morteros (a thick bowl with a mashing paddle used in Latino cooking). Add a little salt to the garlic (more than a pinch, less than a teaspoon). Add the sour orange juice
to the mixture. Add oregano
and pepper, to taste. Brush the Mojo
Sauce on the food as it is cooking.
