Thanks so much for all these ideas.
I'll try out a few soon as I have 4 left over. Charlies one with scallions sounds good as do the roast ones with rosemary, and the bisque one and mashing them with potato, mmm, I'll have to buy more.
I just dont know if we get rutabaggies, dont know what they are, wonder if they are like a dasheen (I have some of those growing in the garden, wonder how they will go with parsnips)
Isn't it such fun finding a veg/food that one never knew before...well not intimately!
