Since the Canadian 241 outlet disappeared from Geylang I've given up on ready made pizza. Making the best pizza from scratch is easier, much faster and muuuch tastier anyway The trick is on the crust. To get a really crunchy crust do the following:
Get a 500g bag of all purpose flour (not breadflour). Put half of the flour in a mixing bowl and add 1 teaspoon of yeast, 1 teaspoon of sugar, 1/2 teaspoon of salt, some pepper and 5 tablespoons of olive oil. Mix it all in thoroughly. Now add lukewarm water (I use Singaporean "cold" tap water which is warm enough). Keep stirring and make sure you don't add too much water. You'll know it's ready when the dough is thick but not dry. Add a bit more flour untill the outside of the dough isn't sticky anymore. I don't use exact measurements anymore because the result is much better if I use my own judgement.
Now comes the best trick: cover the bowl and keep it in the fridge for at least a day. Some people insist on keeping it in a warm place first to let it rise but that depends on your preference of fluffiness. The dough will become elastic like clay when cooled properly.
I'm using a special pizzapan but you can just spread out the dough (thinly) on a baking sheet. It's best to use a non-stick sheet or to use baking paper since oil tends to make the dough soggy. Any leftover dough can be frozen in a bag.
Now for the topping.
The base of every good pizza is a good tomato sauce. I use fresh, chopped tomatoes, garlic, oregano, basil, sugar, pepper and salt. heat it up in a pan and add a splash of balsamico vinegar. Simmer until thick and cool.
Spread a bit of the sauce on the pizza, starting from the center and spread outwards.
Now you can put anything you like as a topping. Great to get rid of that roasted chicken, or chinese sausage. Vegetables, mushrooms, corn, anything that's not too wet can be used as topping. Don't pile on too much because it will cook unevenly.
A pizza wouldn't be a pizza without cheese. I love blue cheese but you can put on Gouda, Mozarella (more authentic) or even those horrible plastic slices they sell at 7/11 (not recommended).
Heat the oven to 250 Celcius, put in the pizza for 30 minutes and enjoy!
