    Preheat oven to 180C. Combine Jerusalem artichoke, shallot, garlic, herbs, lemon rind and juice in a large bowl, season to taste and mix to combine. Add oil, mix to coat, then spread mixture on oven trays lined with baking paper. Roast, turning occasionally, until golden brown and very tender (35-40 minutes). When cool enough to handle, squeeze garlic from skins (discard skins), then transfer mixture to a large saucepan.
