My mother taught me using the recipe in the Better Home & Gardens New Cook Book. It’s still in the 1968 copy I have. It’s in my 2000 edition as well but includes chocolate glaze. You might try googling it as it’s a lot of typing and I’m lazy. I miss my mothers old stove which had a back burner that lowered to create a deep fryer. I still have a scar on my forehead from leaning over while dropping the dough into the fryer.
For maple frosting, if you can find a copycat Tim Hortons recipe, you can’t do any better than that IMO.
Funny you you should bring this up. I’m planning to make bagels for th first time as soon as my yeast arrives.
