• Add ramp greens, arugula, and spinach in big handfuls, cooking and wilting one batch before adding the next. (At first it will look like all those greens will never fit in the skillet, but keep at it-you'll see!) When all greens are wilted (this may take 15-20 minutes), add coriander, salt, and cayenne. Cook, stirring, until spices are incorporated, about 1 minute. Add lemon zest, cream, and 1/2 cup Parmesan. Continue to cook, stirring, until cream has slightly reduced, about 2 minutes longer. Remove from heat.

CABBAGE AND LEEK GRATIN

Steps:

• 1. Preheat the oven to 180*C/375*F. Remove any old and tatty looking leaves from the outside of your head of cabbage. Cut it into quarters and remove the core. Shred coarsely.
• 2. Trim the leeks, cut in half and wash them thoroughly. Shred them coarsely as well. Mix them into the cabbage.
• 3. Bring a large pot of lightly salted water to the boil. Add the vegetables. Bring back to the boil, and then reduce the heat to a simmer and cook them for about 5 to 6 minutes, just until barely tender. Drain in a colander. Make sure you get as much water out as you can. You don't want any to dilute the delicious cream sauce.
• 4. Make your cream sauce by melting the 3 TBS of butter in a saucepan. Stir in the flour and cook, stirring over medium heat, for about one minute. Slowly whisk in the milk and cook, whisking constantly, until smooth and nicely thickened. Season to taste with some salt, pepper and grated nutmeg. Add a splash of hot pepper sauce to taste.
• 5. Put the cabbage mixture into a buttered shallow dish. Pour the cream sauce over top and allow it to soak in for a few minutes, while you make the crumbs for on top
• 6. Melt the 2 TBS of butter and then stir in the bread crumbs, mixing all together well. Sprinkle the buttered crumbs evenly over the top of the casserole. Bake in the preheated oven for 25 to 30 minutes, until nicely bubbling and the crumbs are lightly browned on top. Note - I sometimes add a cup of grated gruyere cheese, plus 1 heaping TBS of grated Parmesan cheese to the sauce to give it a rich and cheesy flavour. You may also add some grated cheese on top if you wish.

Cook the spinach following pack instructions - if you have a microwave, choose this method.
• Put the leeks in a pan with the 300ml milk and the butter. Cook gently, part-covered, for 8 mins until the leeks are tender. (Keep an eye on things as milk can easily boil over.) Mix the 3 tbsp milk with the flour and mustard, then stir into the leek mixture - keep stirring until thickened. Take off the heat and stir in three-quarters of the cheese.
• Squeeze as much liquid as you can from the spinach, then arrange on the base of 2 gratin dishes. Place a fish fillet on top of each, then spoon over the leek & cheese sauce. Top with the sweetcorn mash. Mix the remaining corn and cheese, and scatter on top. Place the dishes on a baking tray and cook for 25 mins until the fish flakes when tested and the top is golden.
