Thank you all, dear forum friends, for your kind and practical suggestions. They are some good, solid tips - very supportive.
Actually, I think there's a niche that Thermomix could exploit if there could be a recipe book meeting this exact need.
Somewhere else on the forum tonight someone else was posting about having such a lot of risotto left, so it's not just a few people facing this issue. Great to have the advice of others. Very helpful and encouraging. Thanks a lot.
