Add roughly 1 tbsp butter to a pan, with diced onion, bay leaves, thyme, simmer for 2-3 minutes.
Add white wine (or whey/grape juice if using) stir and simmer for a few more minutes.
Chop the cod fillet into large cubes.
Strain the broth into a bowl/jug, be sure to squeeze as much as you can from the bunch of thyme, bay leaves and onions. Don’t waste that flavour!
Add the strained broth back to the pan. Add some salt and cracked black/red peppercorns to taste. Add the sliced apple, cream, juice of half the lemon, more butter and the cod. Continue to simmer until the cod has cooked through. 6-8 minutes.
