It took me over 15 years to start getting fruits from these trees I grew from seed in my organic/biodynamic gardens in southern Delaware. I make my own compost with my own animal manures and use no chemicals here for over 45 years now . The whole fruit minus the seed is used with just a little cane sugar to sweeten it. It is cooked down on my wood cookstove in my kitchen . There are many health benefits of bitter oranges .They are high in vit c and bio-flavonoids, good for digestion ,anti-inflammatory and anti -viral . I use them in cocktails, smothies ,baked goods, marinaides and salad dressings .I also sell and use the tinctures I make with the fruits .
