A friend gifted me a large jar of lavender salt several years ago and I'm looking for new and creative ideas for how to use it. Any tips?

I would pair it with goat cheese. And rosemary... Lemon shortbread cookies. Or a sprinkle on lemon rosemary focaccia.

It would make an interesting twist on a salted caramel.

Lavender pairs well with honey, so consider using it in any recipe that calls for honey as either a glaze or a part of the recipe. I'd also be tempted to try it as seasoning for sweeter vegetables like carrots or butternut squash.

Lavender (plain) appears in herbed de provence blend, but in small amounts. Maybe mix up some blend with the lavender salt, package some as gifts, use some for roasting chicken or other poultry. Possible use in making preserved lemons, but check them often to make sure there's enough salt to prevent bacterial growth. Garnish for yogurt or hummus (see Ottolenghi and other books of mid-eastern or southern French cookery).
