Ocado Shallots. Our finely layered shallots have a bright, blemish-free skin and are milder and sweeter than onions. Don't be tempted to substitute onions if the recipe calls for shallots, it won't be the same. Also great peeled, drizzled in olive oil and roasted. Serving Suggestion For a flavoursome accompaniment to any dish, slice shallot in half (lengthways through the root), chop off top and tail then peel. Thickly slice shallot (width-wise) and sauté in a pan until caramelised. Serve with a sprinkle of flat leafed parsley and grated cheese.
