I mix the puree, with the seeds, to the tea and grape juice, and then strain it. It is much easier than trying to strain the thick puree.
I used strawberries instead of raspberries so I wouldn't have to strain the seeds and it tasted great! I made it for a party and it looks very pretty.
This was yummy. The raspberry puree was kind of a pain, though. It didn't just pour through my sieve-I had to actually force it through to separate the puree from the seeds. However, the flavor was very good. I couldn't find a family sized tea bag, so I just threw 5 tea bags in the water-I used green tea.
