Query: Not like it used to be

When growing up Mac was my favorite toffee, but it has changed a lot over the years. Now it is more like those very soft and dry-ish square caramels you can get at any grocery store. True, it doesn't stick to your teeth anymore, but it doesn't have that buttery melt anymore either.If you're looking for a good chewy and firm toffee like Mac used to be, try Walkers' Nonsuch Original Toffee. I tried that recently and was impressed. (As of this review, you can get it here on Amazon as well.)
