Here is the recipe for sauerkraut glass.
400g sauerkraut red or white, we used white but red would be beautiful
110g liquid glucose
40g agave nectar
shake of caraway seeds
65g water
pinch of salt
Cook all ingredients together until the sauerkraut looks transparent and half of the liquid has evaporated. Puree the mixture in a blender until silky and smooth. Strain the mixture through a fine mesh strainer and let cool and rest for at least an hour or overnight. Spread the sauerkraut mixture on a silpat using a template then bake in a 200 degree F oven for half an hour. Check the consistency. If the glass is dry and transparent remove from the oven, take the glass off of the silpat and let cool on a clean table top. If the glass still retains moisture continue to cook, checking every five minutes until the glass is dry. Use as you wish.
