Wash and dry the kumquats thoroughly. Slice each kumquat into quarters lengthwise and remove any seeds.
13 oz Kumquats
Start by boiling a few cups of water in a saucepan. While your water is heating, prepare an ice bath (water and ice in a medium sized bowl).
Ice bath
Once boiling, drop the sliced kumquats into the boiling water and allow them to boil for 2 minutes before removing them and placing them into an ice bath.
Meanwhile, place the granulated sugar and water in a heavy bottom stainless steel saucepan or dutch oven, mix to combine and bring to a boil. Make sure not to mix the syrup after the initial stir, otherwise the syrup could crystallize. The pot matters here, you want to make sure that your syrup will heat evenly!
3 cups Water, 1 ½ cups Granulated Sugar
Once the syrup has reduced and reached a temperature of 218-220F/104C (this should take about 20 minutes using a gas stove), place the kumquats in the syrup.
Continue to heat the syrup and kumquats until the syrup reaches 230F/110C and starts foaming (this should take an additional 15-20 minutes using a gas stove, but make sure to stay nearby in case caramelization starts to happen), then turn off the heat.
Add the split vanilla bean and allow the kumquats to cool in the syrup for 20–30 minutes so the vanilla can gently infuse. If you're noticing that the syrup is a bit too thick, you can add ¼ cup of water to thin it out a little bit!
1 Vanilla Bean
Gently stir in the orange blossom water and then transfer the candied kumquats with syrup to a clean jar or airtight container, ensuring the fruit stays submerged in the syrup. Store in the refrigerator for up to 2 weeks.
