Okay, thanks all.

I will let it rise in the bowl probably.

Bear, okay, so I will look for the baking flour. When a recipe calls for 'x' amount of improver, what should I use? For example, this is the pizza base recipe I have (but am choosing not to use it as it has cheese in the base, so will be an extra $ - I find cheese very expensive , would it work well if I just didn't put the cheese in? That, and I had no idea about what the improver was).

Pizza Base Mix (from the Body Shop Cookbook)

1 1/2 kg plain flour
5 tsp natural improver
1 tblsp salt
2 tblsp dry yeast
2 cups grated tasty cheese
1.1 litres very warm water

Mix all dry ingredients together. Add grated cheese. Pour liquid into dry ingredients.
Mix into a stiff dough. Place in a warm spot (on top of warm oven) to double in size.
Punch down and knead to remove all the air bubbles.
Roll out into the size and shape you want.
Bake for 15 to 20 minutes at 180c in oven with your favourite filling on top.
Makes 2 to 3 medium size pizza bases.
