I have made my mother's custard recipe all my life with perfect results until I moved to 7,000 ft. I cook it in a water bath & have added 10 minutes to the cooking time but the custard is watery! Help!

A baked custard will certainly take longer at higher elevations. Without knowing your recipe, I would say to use a bain marie (water bath) for your custard cups filled up to 3/4 high to the top of the cups. You may need to add moe water during baking time but 35-40 min. should be about right. The custard will be a bit jiggly still but should set completely in the refrigerator overnight. You may also try covering the cups with aluminum foil to help the custard bake more quickly.
Hope this helps. If you still have problems, please inquire again. Thanks for using eXtension.
