Ingredients

For each sandwich:

  • 2 slices rye bread recipe below or use store-bought
  • 5 ounces pastrami
  • 3.5 ounces gruyere cheese thinly sliced
  • 1 tablespoon mustard or more to taste
  • potato chips and gherkins to serve, optional

Make the rye bread or use a good one from the bakery

  • 1 tablespoon dry yeast
  • ¼ cup warm water
  • 1 cup light rye flour finely milled. Medium or dark rye also work, but result in a darker bread.
  • 1 cup white whole wheat flour finely milled. Or use regular whole wheat flour for a darker bread.
  • 2 teaspoons salt
  • ¾ cup buttermilk at room temperature
  • 2 tablespoons malt syrup or molasses
  • 1 tablespoon honey
  • 2 tablespoons sunflower oil or other vegetable oil
  • 2 teaspoons caraway seeds crushed or coarsely ground
  • 1 teaspoon fennel seeds crushed or coarsely ground
  • 1 cup bread flour or all-purpose flour

Instructions

For each sandwich:

  • Lightly toast 2 slices rye bread.
  • Spread one side with 1 tablespoon mustard. Top with 3.5 ounces gruyere cheese, sliced and return for a few minutes to the oven until the cheese begins to melt.
  • Arrange 5 ounces pastrami slices on top of the other bread slice. Top with the inverted slice with cheese. Serve with potato chips and gherkins, if desired.

For the bread:

  • Grease one 9x5 inch (23x13cm) loaf pan. Set aside.
  • In a small bowl mix 1 tablespoon dry yeast and ¼ cup warm water and let foam for a few minutes.
  • In the bowl of the stand mixer, put 1 cup light rye flour, 1 cup white whole wheat flour, 2 teaspoons salt, ¾ cup buttermilk, 2 tablespoons malt syrup, 1 tablespoon honey, 2 tablespoons sunflower oiland yeast mixture. Mix with a wooden spoon until it integrates.
  • Attach the dough hook and start mixing on medium-low speed until a shaggy dough is formed.
  • Add 2 teaspoons caraway seeds, 1 teaspoon fennel seeds and 1 cup bread flour, a few tablespoons at a time.
  • Beat for 6 to 8 minutes, until the dough is elastic but not too stiff. If it's too sticky add a few more tablespoons of bread flour but don't overdo it. It needs to retain some stickiness.
  • Transfer dough to an oiled bowl, cover with plastic wrap, and let rise until doubled, about 1 hour. It can take more time depending on the temperature of your kitchen.
  • On a lightly floured surface, pat the dough down, and then roll it tightly, pinching edges to seal.
  • Place in the prepared pan, cover with a clean kitchen towel, and let rise again until doubled, about 1 to 1 ½ hours.
  • About 20 minutes before baking, preheat oven to 375ºF (190ºC).
  • Bake for 35 to 40 minutes, until golden brown and the bottom sounds hollow when tapped.
  • Let cool completely on a wire rack before cutting.

Notes

Ratio: The amounts of each ingredient given below are an estimate. Adjust to your personal preference with more of this or less of that.
Storing the bread: cover the bread in plastic wrap and store it at room temperature for a few days, in the fridge for a week or frozen for a month (I recommend slicing it first).
