I made a stock from the bones of the thanksgiving turkey yesterday, it slow cooked in the crockpot for a day, put it in the fridge, skimmed off the fat and put it in the crockpot again with some leftover turkey, potatoes, carrots, onions and celery. I threw in some rosmary, sage, a few other herbs and spices. Well, unfortunately, the rosmary, sage and other leafy herbs (though well crushed) keep rising to the top. Is there any way to get them to mix in the soup?
