Step 6: Strain the sauce
Pour the sauce into a sieve or strainer and strain back into your saucepan. I use a screen sieve that has holes about the size of window screen which seems to work pretty well. Smaller and it will be a pain to get the sauce through, larger and you'll get chunks. As it is, you'll need to take a rubber spatula and work the sauce through the screen. Don't forget to wipe the back of the screen when you are done.
