You can certainly double the recipe no problem, but I'd keep the proportions of everything equal. Since you have more, the milk will take slightly longer to warm but not by much. I think 2tsp would give the wrong kind of texture. The only exception is you could make a larger amount of peach puree and then warm it to thicken it up a little. Then let it cool before mixing in. This would give a slightly stronger peach flavor, if you were looking for that.

Thanks, it would be perfect, it's so cooling and light.

Thanks, it really is a tasty combination.

How wonderful to be growing your own peaches - I hope you'll give this a try to use some of them.

Thanks, the fragrant flavor goes really well.

Thank you, I agree they are such a light and easy dessert. Like the idea of fruit syrup in there too.

Thanks, it's deliciously creamy.

Thanks, it's easy to make so do give it a try!

Thanks Barrie, it's so easy and tasty, I hope you give it a try!

Thanks Tara, it's a subtle flavor but it's tasty!

Thanks Camilla - do give it a try with passion fruit, it goes so well!

Thanks Wendy, it's really a very easy dessert and I do love the passion fruit with it.
