Tips for superb torrijas: I find the result is best when you let the bread go very stale before soaking, so that the slices can soak as much milk as possible and yield a very creamy inside afterwards. So what I do sometimes is to slice the bread before letting it dry overnight, to assure that the loaf dries thoroughly (and because slicing is a lot easier while the bread is soft). And I recommend you make sure that the slices soak as much milk as feasible, so it is best to check how they are doing within say 20 minutes after pouring the warm milk on them, because you can always add a little more if the slices have soaked up all the liquid in the dish, say another cup. For me these are indeed the secrets for a lusciuosly creamy interior that looks and tastes more like pastry cream than like plain milk-soaked bread. Because that is what I really love about torrijas, that the alchemy of soaking and frying metamorphoses the simplest ingredients into something different and truly delicious.
