Freezing and Thawing Citrus Ends in an Attempt to Make Oleo Saccharum

Oleo Saccharum, sugar imbued with citrus oil, is typically made with peeled citrus. The peeling seems to be crucial to freeing the oils in the citrus for the sugar to pull it out - you can't just pour sugar over a whole lime and make oleo saccharum. I was curious about making oleo from the ends of citrus after making wheels - those are not typically peeled and would be very hard to peel. Also, for limes that were squeezed (as limes are hard to peel) - same situation. My thought was that if you put the citrus in the... Read more →

Testing Blanched Citrus Wheels for Color Retention in Dehydrated Garnishes

In many online recipes for candied citrus peels, the directions include blanching the citrus in boiling and then freezing water several times in order to "reduce bitterness and retain color." I wondered if the color-retaining properties would carry over to dehydrated citrus wheels, which are a popular way to garnish cocktails with less waste than fresh citrus wheels - as leftover wheels and partially-cut citrus would be discarded at the end of each night. Dehydrated citrus wheels often turn brown and don't taste good, so I was seeking ways to improve them. So I did an experiment: I compared dehydrated... Read more →
