Few things in life can compare with a St. Viateur bagel hot from the oven. It is one of life's greatest simple pleasures, and should feature on Maslow's hierarchy of needs.
I love poppy and sesame. I beg friends and family to mail me bagels from St. Viateur. They freeze well and toast up nicely.
If you're going to freeze them, cut them when they're still fresh and THEN freeze them. But they are best hot and fresh and melt-in-your-mouth perfect.
