There are a few things you can try: >>>Push the turnip puree off to the side in the pot and let it sit for a while. The excess liquid will separate from the mashed turnips and you can remove it with a ladle or turkey baster. >>>If carbs are not a problem, add some potato starch or flour. Start with a tablespoon then try one more. Make sure the mashed turnips are still good and hot because you don't want to consume raw flour. This food starch product is amazing for this purpose: Cornaby's EZ Gel Instant Food Thickener. >>>Place uncovered in a 350-degree oven for 10 to 15 minutes. The dry heat of the oven will help evaporate some of the liquid.
