Putting together this box was actually the first time it occurred to me an explanatory website might help, because I could just imagine someone opening this box and going, “What the hell are these things??”
These things are dried lemon peel and lavender. They make delicious things. You can use them to infuse black tea, olive oil, sugar, or pepper.
You can also use them in this recipe. (You’ll have to make your own lavender sugar for that — take the lavender, layer it with 1/2 cup of sugar in a clean glass container, cover it securely, and let it rest for a day. Then shake to distribute the lavender et voilà.)
