Did you ever heart this name? It’s a small fruit from the citrus family. I have to admit, I’ve never heart of them before. The fruits look similar to very tiny oranges in color and structure, but the shape is a little bit like a long drawn-out egg or an olive. Their size is similar to a large olive or a date (fruit of the date palm)
You can’t eat them. They are very hard. But, the people got the idea to cook them very long. After about 2 days of cooking the fruits are edible and taste quite good. Now, they are sweet. You can get them candied or pickled in kumquat sirup. We tasted both variants. The candied variant was way too sweet in our opinion, but the pickled ones were good. We bought a 500 ml glass to take them home. The dealer (and producer) told us, even the open glass is good for another year. Thus, you don’t have to eat them all at ones. That’s good. In my opinion, you can’t eat more than two or three of them.
Other usages for the kumquats are making marmalade, syrup or liquor.
