Steps
Step 1
Scrub the potatoes clean and place in a small saucepan with water and 1 tablespoon of salt. Bring to a boil and simmer the potatoes for about 10 minutes.
10 min
Step 2
Turn off the heat and let the potatoes stand in the water for 5 minutes. Drain the potatoes and allow to cool slightly.
5 min
Step 3
Remember that potatoes come in various sizes, so the cooking time may vary – if they do not easily glide off of a fork when speared and lifted out of the water, they are not done yet. Fry bacon slices and transfer to a dish lined with paper towels.
Step 4
Peel the red onion and slice in thin rings. Transfer the flour to a bowl and toss the onions in the flour.
Step 5
Remove onions and shake off excess flour. Heat the oil in a saucepan over medium heat.
Step 6
You can test whether the oil is hot enough by adding a small piece of onion to the saucepan. If the oil bubbles around the onion, the oil is ready.
Step 7
Transfer as many onion rings to the saucepan as can fit in one layer. Do not add too many onion rings at once.
Step 8
Fry the onions for a couple of minutes until they are golden brown. Transfer onions to a dish lined with paper towels and sprinkle with salt.
2 min
Step 9
Repeat the process until all onions are fried. Butter a slice of dark rye bread and arrange round potato slices (or, if the potatoes are very small, halved potatoes) on top.
Step 10
Top your open potato sandwich with a good mayonnaise, crispy fried onions, fried bacon and sliced chives.

Cook time changes. Sweet potato browns faster.
onion → shallot
Shallots are sweeter. Use the same volume, or a little extra onion if that is what you have.
flour (a gluten-free blend (not plain rice flour alone for bread)) → a gluten-free blend (not plain rice flour alone for bread)
Coatings and roux can swap. Yeast breads need a blend designed for gluten-free baking.
