Notes
Lamb Loin Chops: Look for fresh chops that have a pinkish-red color (not brownish-red) with a fine marbling of fat. They should be cut evenly, about 1 1/2" thick, for even cooking.
Olive Oil: Use good quality, extra-virgin olive oil for the best flavor.
Dried Herbes de Provence: Choose a trustworthy brand that offers a blend of high-quality dried herbs like thyme, rosemary, oregano, and lavender for the best flavor.
Dijon Mustard: Check the ingredients to make sure it contains real Dijon mustard seeds and avoid overly processed versions with added sugars and fillers.
Fresh Garlic: Select bulbs that are firm, plump, and heavy for their size, with no soft spots or green sprouts for the freshest taste.
