Back from the bellarine with yet another big bag o' lemons. Never ends! will have to give more away.
Starting to get thoughts about doing icy poles though.
Basically squeeze them into ice cube trays. thaw them out come summer. Chuck it in moulds (with water / sugar and some berries).. wait for it to freeze. Grab a drill, pour liquid-ish icecream in the holes, partially re-freeze, jab the stick in, then back in the freezer... hrmm.
If you have an electric kettle, chucking the leftover peel/skin/remnants into the kettle and boiling it twice (30mins break in between) is a great fuss free way to clean it! Less recommended if you have the type with a coil inside.
iherb has it, so does colesworth (sometimes). Sometimes called Cream of Tartar. Tartaric acid is made from grape stalks and leftover wine making trash, so beer kit makers will have it too (probably). Used in baking too.
