My poncirus fruits are large and juice filled like yours. I squeeze the juice out, boil it, settle out the bitter oils in fridge overnight, siphon off the juice leaving oil behind, and put juice up in freezer in cup-size containers, and take out one container a week or so and mix it with water in a orange juice carafe and sweeten to taste with stevia. It makes a strong lemonade that I drink every morning out of a small orange juice glass.
