This is my grandfather's recipe - he uses quite a novel ingredient to simulate the 'brown bread', and it works a treat!
Maple flavouring gives a touch of maple syrup flavour and is available to purchase online or from specialty shops. In a pinch, try using maple syrup (though the maple flavour won't be as concentrated).
Just a comment really, because I've never tried this recipe. I thought people might be wondering why this is called "brown bread ice cream" when there is no brown bread in it. Well, brown bread ice cream is an old British treat and certainly did not contain Grape Nuts! You literally made your own toffee-flavored chunks by combining brown bread crumbs with sugar and caramelizing them in the oven. Then blend with traditional vanilla base ice cream ingredients for a unique frozen dessert. - 22 Jun 2007 (Review from Allrecipes US | Canada)
Grandpa B's recipe is the best! We like to use pasturized egg product instead of raw eggs. - 09 Jul 2005 (Review from Allrecipes US | Canada)
I have tried every flavor of ice cream over the years but nothing excited my tastebuds like this. A truly wonderful find. I shared this recipe with my family along with a dish of ice cream. I should have kept this one a secret. - 31 May 2002 (Review from Allrecipes US | Canada)
