Remove the bagels from the refrigerator 60 to 90 minutes before you plan to bake them,
Immediately check whether the bagels are ready for baking using the “float test”: Place one of the bagels in a small bowl of cold water.
If it sinks and doesn’t float back to the surface, shake it off, return it to the pan, and wait for another 15 to 20 minutes, then test it again. When one bagel passes the float test, they’re all ready to be boiled. If they pass the float test before you are ready to boil and bake them, return them to the refrigerator so they don’t over proof.
About 30 minutes before baking, preheat the oven to 500°F (260°C) and gather and prepare your garnishes (seeds, onions, garlic, and so on).
To make the poaching liquid, fill a pot with 2 to 3 quarts (181 to 272 g) of water, making sure the water is at least 4 inches deep. Cover, bring to a boil, then lower the heat to maintain at a simmer
. Stir in the malt syrup, baking soda, and salt.
Gently lower each bagel into the simmering poaching liquid, adding as many as will comfortably fit in the pot. They should all float to the surface within 15 seconds. After 1 minute, use a slotted spoon to turn each bagel over. Poach for another 30 to 60 seconds,
on a generous amount of whatever toppings you like as soon as the bagels come out of the water then use the slotted spoon to transfer it back to the pan, domed side up. (It’s important that the parchment paper be lightly oiled, or the paper will glue itself to the dough as the bagels bake.) Sprinkle the top of bagels with seeds of your choice.I used black poppy seeds and sesame seeds
Transfer the pan of bagels to the oven, then lower the oven heat to 450°F (232°C).
Bake for 8 minutes, then rotate the pan and check the underside of the bagels. If they’re getting too dark, place another pan under the baking sheet. (Doubling the pan will insulate the first baking sheet.) Bake for another 8 to 12 minutes, until the bagels are a golden brown.
Cool on a wire rack for at least 30 minutes before slicing or serving.
