People love it as a light breakfast or a quick weeknight dinner, and it is the kind of humble, wholesome food that has been on Czech tables for generations.

➜ Tip on where to find Czech rye bread in America (or at least a close alternative)

The right bread is truly the foundation of this sandwich, and while authentic Czech rye bread can be hard to track down in America, do not let that stop you.

Your best bet is to look for a store that carries European food. When I visited Washington D.C., we found a great option at Lidl that came quite close to the real thing. Also, do not underestimate your local bakeries. Chances are there is a Czech, German, or Polish baker in your area. It is worth doing a little research!

Or better yet, bake your own - here is my Czech rye bread chleba recipe to get you started.

➜ How to make this Czech sandwich

STEP 1: Bring water to a boil over medium-high heat. Add a teaspoon of vinegar - if an egg cracks, the vinegar will prevent the whites from spreading in the water. Also, the vinegar helps peel them easier.

Put the eggs carefully in the water, then reduce the heat and let simmer for 11 minutes. Transfer the eggs to a bowl of cold water and let them cool for at least 5 minutes. Peel and slice into rounds. Best peeled when the eggs are still a bit warm.

STEP 2: Take your slice of rye bread and spread a nice layer of softened butter all the way to the edges. Do not be shy with the butter, this is the foundation of the whole sandwich!

STEP 3: Arrange the egg slices on top of the buttered bread, slightly overlapping them for a nice look.

STEP 4: Sprinkle a little salt over the egg slices, then scatter the freshly chopped chives on top.

STEP 5: Serve immediately and enjoy as a light breakfast or a quick weeknight dinner. Best eaten fresh!

➜ Variations and tips

Want to take it up a notch? Here is what my family and other Czech home cooks love to add:

• Mustard - spread a thin layer of mustard on the butter before adding the eggs. Dijon works beautifully. This was by far the most popular tip in the Czech community!
• Pickled cucumber - lay a few thin slices of dill pickles on top of the egg for a tangy kick that cuts through the richness of the butter and egg.
• Lard instead of butter - old-school Czech cooks swear by spreading lard (sádlo) instead of butter for an even more traditional flavor.
• Grated hard cheese - sprinkle a little on top for extra richness.
• Horseradish - grate a little fresh horseradish right over the top for a sharp, bold finish.
• Tomato - add a few fresh slices alongside the egg for a lighter, summery version.
• Ketchup - toast the bread first, spread with ketchup, then top with the egg. A beloved childhood combo for many Czechs!
• Green onion - a great substitute if you do not have fresh chives on hand.

➜ Storage tips

• Hard-boiled eggs - once cooked, unpeeled eggs will keep in the refrigerator for up to one week. However, from my experience, fresh and still lightly warm eggs peel better.
• Assembled sandwich - this sandwich is best eaten fresh and does not store well once assembled. The bread will go soggy, so put it together only when you are ready to eat.
