French bistros have known for a century that butter cultured with live bacteria before churning tastes sharper and deeper than the sweet-cream kind, and it turns out that same fermentation gives your gut something to work with too. Pair it with peppery radish slices and flaky salt and you get a snack that punches way above its four ingredients. It's one of several fermented toast toppings worth keeping in rotation, alongside labneh with za'atar oil and sauerkraut and Swiss cheese.
Ingredients
- 4 slices crusty sourdough bread
- 4 tbsp cultured butter, softened
- 6-8 radishes, thinly sliced
- Flaky sea salt
- Cracked black pepper
- Fresh chive or dill fronds for garnish
Instructions
- Toast the sourdough slices until golden and crisp at the edges.
- Spread a generous layer of cultured butter over each warm slice, letting it soften slightly into the bread.
- Arrange overlapping radish slices on top.
- Finish with flaky salt, cracked pepper, and a scatter of chives or dill.
- Serve immediately while the toast is still warm.

Why This Is Good for Your Gut
Cultured butter is churned from cream fermented with Lactococcus lactis and Leuconostoc mesenteroides, and trace amounts of these bacteria and their metabolic byproducts, including butyrate precursors, carry into the finished butter. Sourdough bread's slow fermentation also breaks down phytic acid and some gluten proteins, making it gentler on digestion than standard yeasted bread.
Toast, but make it interesting for once.
