i'am looking to buy some pork blood to make some sausage, does any one know where i can get it?
You should be able to find it in any filipino store. There's a filipino store next to sherbourne station called Cozy Corner (8 Howard Street) that sells it frozen.
If you live in the Mississauga area, I've seen it in a large store called Grant's on the Northeast corner of Dixie and Bloor. It's an Asian supermarket with all kinds of interesting things.
