While I like pizza at restaurants, it is also great to have at home. It is good for one person or large groups. You can make your own, get quality take-and-bake, have it delivered, or have a BYOP (bring your own pizza) party. Superbowl Sunday is always a record pizza sales day in the USA.
When you have pizza with a group, the only other things you really need are beverages and napkins. Since I tend to like pizzas with strong flavors (such as anchovy, garlic, pesto, etc.), I usually drink a full-bodied red wine (Cabernet Sauvignon, Shiraz, Chianti), an oaky Chardonnay, India Pale Ale, or even hot coffee. However, food pairing is an art not a science, so just have whatever you like.
Pizza is not just for adults. You can have a pizza themed birthday party for children. There are sample and template invitation cards available via Google. If your child's friends are young or particularly messy, you can have the party outdoors.
If you decide to make your own pizza, you can:
Make your own crust (from scratch, Bisquick, or other mix),
Buy pre-made dough (from Trader Joe's or Whole Foods - I typically go this route),
Buy frozen pizza dough (Pillsbury, food service companies, etc.),
Buy pre-made pizza crusts (Bobili or Rustic Crust who has some which are Gluten Free - Both of these sites have recipes).
In addition to your crust, you will typically want tomato sauce (some people use pasta sauce), Mozzarellacheese, and other desired toppings.
Some popular toppings include: Anchovies, Artichokes, Arugula, Baby spinach, Black Beans, Broccoli, Canadian Bacon, Capers, Cherry tomatoes, Chicken Curry (my favorite), Chorizo, Crayfish, Duck, Eggplant, Feta cheese, Fresh basil, Green peppers, Ham, Jalapeño peppers, Mushrooms, Nettles, Olives (green and black), Onions, Pepperoni, Pesto, Pine Nuts, Pineapple, Prosciutto, Roasted Garlic, Roasted Red Peppers, Sausage (pre-cooked and drained), Shrimp, Squid, Sun-dried tomatoes. It is good to have anchovies available because there are always interesting discussions between the people who love them and those who hate them. Red Pepper Flakes, Parmesan Cheese, and Tabasco Sauce are appreciated condiments for use at the table.
Do all your slicing, shredding, and other preparation in advance. Making pizza is something that will make you appreciate having a food processor.
A pizza stone is very helpful for making good pizza at home. Some people use quarry tiles to hold more heat in the conventional kitchen ovens. Some people swear by cooking pizza in the Weber BBQ Kettle. Sometimes I make it in my BBQ Galore Grand Turbo propane barbeque.
You should have a 4 inch pizza cutter wheel - you can usually get decent quality for a low price at restaurant supply stores. I sometimes use a Lazy Susan as a cutting board and for sharing slices around the table.
Have fun and enjoy your pizza!
