This is what I'm using for my rye bread in the bread machine. Overall it's tasty and rises okay, but the top sinks a little bit, and is really rough.
1 ⅓ warmish water 1.5 cups regular flour 1.5 cups rye flour 1 tablespoon fennel 1 teaspoon salt 1 teaspoon yeast
I'm not using a heatlamp, the bread machine model is the Breadman 2 lb Professional Bread Maker, Stainless Steel, BK1050S (about a month old). The temperature in the house now probably ranges from 67 to 69. I have it on the regular white bread setting in the bread machine.
Any thoughts? Here's a photo - https://imgur.com/a/tU70DRw
