I have a recipe for 3 Seed Bread from RecipeLion. that calls for dry milk powder. Can I omit it? Is there a substitute for dried milk?

I would just skip over the powdered milk ingredient. Seems many older recipes called for the use of it. If the recipe calls for the use of water, replace the water with milk.

For yeast breads, milk that has been scalded has an enzyme that actually helps with rising. If sugar isn't used in the dough, brushing the shaped loaf with milk will help the loaf brown. Besides those 2 points, I don't really know what the need for any milk product in a bread would do.

Traveler, can you post, copy and paste the recipe here? Seeing exactly what type of seed bread it is and the other ingredients would be a big help before drawing any conclusions.

is this a bread machine recipe?

fluid milk or water can be substituted in many recipes -but like IC said - it's easier if we can see the recipe
