I haven't been feeling well today and I came on here looking for a post from you to cheer me up. And here you are sharing a beautiful story π. I love the photograph of you and your grandmother, that's lovely.
A few years ago I was the host for a young Japanese women (she was fourteen, just about to become fifteen). She loved English puddings and took lots of recipes for the ones that she liked. Her favourite was pineapple upside down pudding but she told me that Japanese kitchens don't have ovens, so we experimented (many times - it's a delicious pudding) with making it in the microwave so she could make it for her mum when she got home.
I'm glad that you've come through to where you want to be.
