Mackintosh's Toffee really has no connection to Christmas except that Marion sent boxes of it when she lived in Canada. It's wonderful buttery stuff that came in a red plaid box. We hoarded it, tho I don't remember "getting up in the night for it". I do remember buying it at Glacier National Park when I worked there in the late 60s, and that it was 25¢ a bar.
Anyway, it reminds me of Christmas, and that's gut genug. Hope yours is a delightful one...!
