I did make this a couple of years ago. It worked pretty well. Was quite runny, and very sweet, but I seem to recall I enjoyed it. I imagine it might not work as well with strawbs, just because they are a bit more robust than rasps IYSWIM. But perhaps if you chopped the strawbs up a little bit first? If it doesn't work, you'll just need some vanilla icecream to go with your strawberry sauce!
