In a large sauté pan over medium low flame add a lug of olive oil. Add the sliced onions with a pinch of sea salt and sauté until Caramelized, about 45 minutes. About half way through cooking add the honey and a little bit of water to deglaze the pan and keep the onions from burning. Stir often.
Add the chanterelle mushrooms to the pan with the onions. Season with a pinch of sea salt and sauté together for a few minutes until the chanterelles have wilted. Adjust seasonings to your taste with more sea salt and keep warm.
Meanwhile cook the potatoes.
Cut the potatoes into wedges and add them to a big pot together with the rhyme and bay leaf. Cover with cold water and bring to a simmer. Add 2 tbsp of sea salt. Cook potatoes for about 15 minutes until al dente. Drain in a colander and allow them to dry in their own steam for a few minutes.
Add the potato wedges to the pan with the Caramelized onions and chanterelles and gently give them a toss to coat. Add more olive oil if desired.
In a separate skillet melt the salted butter on medium flame and add the sage leaves. Cook together until the sage leaves are crispy and the butter is browned taking good care not to burn it.
Transfer the crispy sage leaves to a paper towel lined plate do drain.
Add the potatoes and chanterelles to a serving bowl and sprinkle with the crispy sage. Just before serving drizzle the brown butter over the top as well.
