Found in the kitchen of our new house: a rack the size of a standard oven. Any ideas? There’s no way I’m throwing this away; I better know what this is

1 tsp freshly cracked black pepper

2–3 tbsp dried herbs (thyme, rosemary, oregano)

Optional: citrus slices for aromatic infusion

Optional: parchment paper or silicone mats to line trays

Optional: kitchen thermometer for precise cooking
