I come from one of those families where the Thanksgiving menu is essentially written on stone tablets. Many years ago, it was declared that there shall be turkey with stuffing (some cooked inside the bird and some cooked outside). Mashed potatoes are compulsory, as are sautéed Brussels sprouts, homemade gravy and cranberry jelly in the shape of a can.
When I was 12 years old, my cousin Jeremy brought an unscripted dish to our Thanksgiving table, but it was so wonderful that it was added to the holiday canon. It was a very large bowl of steamed and mashed butternut squash, enriched with a bit of powdered ginger and plenty of butter.
The only issue with this squash dish is that we somehow always manage to make so much of it that it ends up being totally out of proportion with the rest of the leftovers. The only thing that ends up outlasting is the gravy. (My father has trouble making less than a gallon of gravy.) Thankfully, I’ve discovered just the thing to transform all that squash and make it the most sought-after leftover around (though, if you make something else out of it, can it still be called a leftover?).
