Scented sugar adds a subtle perfume and flavor to coffee, fruit desserts, and baked goods. Layer granulated sugar with aromatic edibles like scented geranium leaves, rose petals, orange and lemon peel (first set out for a day to dry), or vanilla beans. Mix small batches, and let them sit for a few days in tightly sealed jars while the scents infuse the sugar. One jar or a trio serves makes an unusual present for whomever you think could use a little sweetness.

I wonder if a simple syrup recipe mixed with these options, then strained and put into smaller glass jars may be a more sterile option.
