Kiwi juice made in a blender with two peeled kiwis, water and sugar to taste, in about ten minutes. The one thing that matters is not over-blending: crushed kiwi seeds turn the juice bitter, so stop as soon as it is smooth. Ripe fruit needs almost no sugar. Serves two.
Kiwi seeds are what make the juice bitter, and only once they are crushed, so keep the blending short. Removing the white core before blending helps too, since it is firmer and slightly bitter on its own. If a batch still comes out sharp, a fine strainer takes out the seed fragments in one pass.
