So often recipes only call for the vanilla seeds, while the entire pod is edible. You can use spent vanilla pods to get a fragrant salt from something that otherwise may have been destined for the compost pile. Use Vanilla Salt on cakes, cookies, fresh fruit, and my favourite—sliced tomatoes.
Leave vanilla bean out on the counter for a couple of days to dry. In food processor or spice grinder, process bean until fine. Stir into salt.
