My favorite part about Thanksgiving is always the desserts. Pumpkin pie and pecan pie are my favorites, but squash pie is my personal specialty. But all the Thanksgiving pies are very much American specialties. You can't really find pie as popular anywhere else in the world. The first Americans, the pilgrims, who celebrated the holiday did not automatically think to make pies out of the land's native squashes and pumpkins. They were more apt to eat meat pies for a main dish and custards for dessert as was the tradition in Europe, but because of scarcity, they had to use the plentiful crops for something. Some bright individual combined pumpkins, pie, and custard and came up with the basics for the recipes we follow today. I sincerely thank that individual.
There's just something special about fall and winter squashes, their unique shapes and earthy flavors, that makes me want to cook and bake with them. Since I prefer the more mellow flavor of squash to pumpkin, I use acorn or butternut squash. Sometimes I steam or roast them for this recipe, but canned squash or pumpkin works perfectly well. Since it's synonymous with the holiday, it's the only time I use a can all year. This recipe is very quick and easy. The squash custard is whipped in one bowl. A machine isn't even required. So, do not buy a pumpkin pie from the bakery or frozen section of the grocery store. And whatever you do, don't buy frozen pie crust either. This pie with its cornmeal crust is much more unique than anything available in stores. Serve with a dollop of fresh whipped cream and your guests will be delightedly pleased with Thanksgiving dessert.
Whenever my sister-in-law comes to visit, she tries to sneak in rum balls. There's a deli near Union Square that sells them and it must be sending out a homing signal. A rum ball beacon. It doesn't matter what we're doing or where we are, it's only a matter of time before she says "who wants to go get rum balls!" It's not really a question so much as a rallying cry. 
There was a long line at the meat case this Saturday at the grocery store and I was standing with the crowd. I enjoyed asking everyone in line how they make ‘their’ Tortiere pie. I was in the company of experts - it’s a serious subject in Maine.
Cinco de Mayo is not necessarily celebrated as a national holiday in Mexico, but here in the United States it's a celebration of Mexican culture and a day where no excuse is needed to fill up on Mexican favorites. Guacamole, tacos, and margaritas are all popular when May 5 rolls around, but what about dessert? One of the most popular Mexican desserts is tres leches cake, a sponge cake made of three types of milk, hence the name. Sweetened condensed milk, evaporated milk, and heavy cream make up this incredibly sweet cake.
Another classic Christmas cookie - Shortbread is a traditional Scottish dessert that consists of three basic ingredients: flour, sugar, and butter. According to Wikpedia, this cookie resulted from medieval biscuit bread, which was a twice baked, enriched bread roll dusted with sugar and spices and hardened into a soft and sweetened biscuit called a Rusk.
