The kumquats, also called chinese oranges are grown at our farm. Our batches are made once the fruit flowers and we can collect enough to make a batch. The kumquats add that extra bitterness to the taste making it a delicious marmalade to have with hot buttered toast, used to make some fun cocktails, add as a thin topping to plain cakes and that sweet bitterness makes for a delicious mouthful.
No added preservatives. A lovely bitter tinge. Home made and in small batches. Limited jars because we just grew a few trees. :)
