Prep the carrots: Peel and slice into even pieces so they cook at the same rate. Coins cook fastest; batons look elegant.
Heat the pan: Set a large skillet over medium heat. Add olive oil.
Sauté to start: Add carrots and a pinch of salt.
Cook 4 to 5 minutes, stirring occasionally, until they start to brown on the edges.
Soften with a splash: Add 2 to 3 tablespoons of water or broth. Cover and steam for 3 to 4 minutes, until the carrots are crisp-tender.
Build the flavor: Uncover. Add garlic, ginger, and red pepper flakes.
Stir for 30 seconds, just until fragrant.
Make the glaze: Stir in soy sauce and honey. Toss to coat. Let it bubble and reduce for 2 to 3 minutes, stirring, until the liquid turns glossy and clings to the carrots.
Finish with butter and acid: Turn off the heat.
Add butter and rice vinegar or lemon juice. Swirl until the sauce is smooth and shiny. Taste and season with black pepper and a pinch more salt if needed.
Garnish and serve: Sprinkle with sesame seeds and scallions or parsley.
Serve warm.
