Homemade Noodles with Poppy Seeds

4 eggs
1 teaspoon salt
2 1/2 to 3 cups all-purpose flour
1/2 cup butter
1 small onion, chopped
2 teaspoons poppy seeds
1 tablespoon oil

In large bowl, beat eggs with salt. Beat in 1 cup flour. Continue adding small amount of flour. When no longer able to mix in flour, turn dough onto floured surface and knead in additional flour until dough is smooth and no longer sticky, about 10 minutes. Cover dough with a bowl and let rest for 1 hour.

Divide dough into fourths. With rolling pin, roll one portion into a rectangle 1/8 inch thick. Dust with flour and tightly roll up jellyroll fashion. With sharp knife, cut into 1/8-inch slices. Uncurl slices and set aside. Repeat process with remaining dough.

In small saucepan, melt butter and saut? onions until soft. Add poppy seeds. Stir and set aside.

Add oil to large pot of boiling water. Cook noodles until tender. Drain and toss with poppy seed mixture.

Variation
