The wife recently was given some milk kefir 'grains' which are more of a slurry than a grain. The mixture gets kind of firm, she stirs it up and strains it thru a sieve. When you strain it thru a sieve, the part that stays in the sieve is kinda lumpy (not very); but the runny part still looks the slush from cottage cheese - no lumps or 'grains to speak of, just a thick milky white slurry. It tastes like plain kefir, (think runny yogurt), it isn't real thin, kinda like kefir in the store looks, but it will separate so you have a drinkable part and the slurry part. She has since bought some other milk kefir grains and she says that that is looking more and more like her water kefir grains (I guess it takes a while for them to grow, or whatever they do).
Any idea of what this slurry stuff might be? Is it just weak/worn-out grains? I thought it might be for Cottage cheese or something, but I know Zip about this kind of stuff! I brew the beer, she makes the cheese, yogurt, and kefir <|;>)
