Cajeta
I think of cajeta as the risotto of dessert sauces, since it’s made on the stovetop and requires vigilant attention while it simmers and transforms itself from ordinary ingredients (milk and sugar) into a deeply browned, sticky-sweet paste. The first cajeta I tasted was made in Mexico from goat’s milk, and it was absolutely the best thing I’d ever tasted. Since you might not be able to find goat’s milk, or it may not be to your taste, cow’s milk makes yummy cajeta as well. Begin your cajeta in a very large pot, with a capacity of at least 8 quarts (8 liters), since the mixture can bubble up unexpectedly. It should be a heavy-duty pot with a thick bottom. Be sure to pay attention while you’re cooking it, especially during the last 20 minutes, when it’s vital to keep watch. If you don’t stir it constantly during that final stage of cooking, it’s likely to scorch on the bottom. If it does, simply strain it to remove any browned bits.
