Keep white pith on the flesh rather than the peel to reduce bitterness while maintaining peel structure during candying.
Ensure peels don't touch on cooling rack to prevent sticking and uneven drying.
Adjust citric acid by half tablespoon increments to find your preferred sourness level.

FAQ
Can I use just one type of citrus?
Yes, any single citrus works well though mixing varieties creates more complex flavor profiles and visual appeal.
What if my peels are too bitter after candying?
Next time boil an extra round or two, and ensure you're removing most white pith from the peels before cutting.
How long do these keep and can I freeze them?
They keep 4 weeks in airtight containers at room temperature. Freezing changes texture, so refrigeration is better for longer storage.
