This sounds like something to try. Hardly needs a recipe but here's one.
8 small or 4 medium (16 to 21 oz) waxy potatoes, such as Yukon Gold, Baby Dutch Yellow, baby red, or fingerling, skins intact, scrubbed
2 tablespoons olive oil, plus extra to drizzle
1 tablespoon coarse kosher salt, or to taste
4 garlic cloves, finely chopped
Wine vinegar, to drizzle (optional)
Instructions
Preheat oven to 400°F (204°C).
Place potatoes in a medium bowl and pierce them all over with a fork. Drizzle the olive oil over the potatoes, add the salt and gently toss until potatoes are well coated.
In a shallow baking dish, arrange the potatoes in a single layer without crowding them, and bake until tender, about 1 hour.
Using a pestle or the bottom of a glass tumbler, punch down each potato hard enough to break it open. Scatter the chopped garlic in the opening of each potato. Drizzle with olive oil and vinegar, if desired. Serve immediately.
