TAHOE/TRUCKEE, Calif. – Mix tradition with new techniques to add a fresh twist to Thanksgiving favorites.”Each family is different, but we all share a root in certain traditions,” said Standards of Excellence Chef Rachelle Boucher. “My Celery Root, Potato & Apple Puree and Savory Butternut Squash & Herb Crumble are easy to make in advance, perfect for all ages and a compliment to all Thanksgiving feasts! These recipes work especially well by using a convection oven, such as KitchenAid or Wolf, which bakes ingredients all the way around with a flawless result each time.”Savory Butternut Squash & Herb CrumbleIngredients:4 pounds of squash, (approx. two small) peeled and cut into 1/2 inch cubes, olive oil, salt and pepper, nutmeg, shallots, parsley, vegetable or chicken stock.For the topping: flour, sugar, thyme, salt, butter, eggs and ice water.Directions:Toss the squash with 3 tablespoons of olive oil and place on parchment-lined sheet pan. Roast in convection oven at 375 for about 25 minutes until browned and soft (400 in a conventional oven). On the cook top, saute the sliced shallots with 1 Tbsp. olive oil until translucent. Toss squash and shallots into a large bowl, add parsley and stock, season with salt, pepper, and nutmeg, mix and divide into small buttered dishes or a medium-sized baking dish. Cover with foil and bake until tender about 25 minutes.To make the crumble, put flour, sugar, thyme and salt into a medium bowl, stir and add cold butter, mixing with your fingertips to resemble coarse meal. Keep the butter cold! Whisk yolks with 3 tsps. ice water and add to flour until just combined, adding just a bit more water if needed. Refrigerate squash and topping.Before serving, divide topping over dishes and bake again for about 30 minutes or until topping is golden brown.Celery Root, Potato & Apple PureeIngredients:Potatoes (1 1/2 lbs.), celery root (2 lbs.), 2 Granny Smith apples, butter, nutmeg, salt, pepper to taste.
