Bring a little French bistro style to your table with this perfect date night dinner. What’s the chef’s secret to faultless crispy-skinned salmon? Cook it skin-side down, then swirl more butter in the same pan and toss in some tender chat potatoes and crunchy roasted hazelnuts. Serve it with a quick side of lemon and garlic cabbage, then plate up with a posh lemon ‘cheek’ as a final flourish.
