Hi Wanda, no it dosent need the brown sugar twin - in fact I didn't put it in - I have it but find it has a funny taste so hardly ever use it. Yes, I've used a couple of different types of squash in it - I made a lot of squash soups when I was on Montignac. They all taste pretty similar - though of course I mess around with the spicing all the time so it never really tastes the same twice - it all depends on the mood I'm in when I cook

Edit - I never add the cheese either (but you probably knew that )
