Barry,I too am diabetic and lemon cheesecake is good, use Nairns - they're the biscuits I use, sugar free digestive or the ginger ones, they give a great kick - baileys cheesecake is over-rated in my opinion. use xylitol as a sweetener (if you have a dog though, do not share with the dog or give it as treat - xylitol is toxic for dogs)
Use 100gm digestive biscuits, the nairns if you decide on them
50gm melted butter
Tub light creme fraiche or sometimes I go for greek yogurt (150gm)
180gm light cream cheese (philidelphia)
Lemon - juiced and zest
xylitol or sweetener of choice, as you are mixing it, just keep testing if it is sweet enough to your liking
To make up the cheesecake,
put the buttered biscuit mix into cheesecake tin or ramekins if you are gonna serve it seperately to family
Mix the cream topping and squeeze of lemon juice
place on the biscuit mix and let chill
Decorate with lemon curd if you have some or candied lemon pieces - you don;t have to eat them
It's a nice cheesecake for everyone, even diabetics
