Sit one of the salmon fillets, skin-side down, on a large sheet of foil or baking parchment. Scatter with the lemon slices, herbs, shallots and seasoning, then sit the second fillet on top skin-side up. Tie in 2-3 places with string to secure, splash with wine and fold up the foil or paper to seal. Can be chilled for up to 3 hrs.
Place on a baking sheet and bake for 50 mins-1 hr until the salmon is cooked through check by poking a knife into the fillets and making sure the flesh flakes easily.
Serve in foil or paper on a serving plate, or carefully lift out using a couple of fish slices. Slice into portions and serve with the Lemon & chive mayonnaise and New potatoes 'Lyonnaise' (see 'Goes well with' recipes) and half-steamed broccoli (see below).
