Toasting slivered almonds is easy to do and adds a great deal of depth to their flavor. The hardest part about toasting almonds is to watch them closely so they don’t burn. To toast slivered almonds, spread the almonds in a single layer on a dry, shallow baking dish or cookie sheet. Place in a preheated 350° oven. After five minutes, remove the pan, shake to rearrange the almonds, and return to the oven. After another five minutes, check the almonds again. If they are dark enough, remove them from the oven. If they need a little more browning, shake again and return to the oven. Check every couple of minutes to avoid overcooking. Overall, the almonds should roast for 10-15 minutes. When toasted, the almonds will be just barely darker than they were raw; they should not be too dark.
