Bulk Barn now carries an unbranded erythritol-stevia blend. (Those are its only ingredients.) It’s over $10/lb, which is relatively expensive, but of course I can hold out for the $3 off $10 coupons and get it for around $7/lb.
(I was at Bulk Barn with a $3 off $10 coupon to pick up baking powder, cinnamon, cardamon pods, and loose tea. One good thing about being on a budget is that it keeps me away from the maltitol-sweetened chocolates. I’m satisfying my desire for chocolate with homemade hot cocoa.)
