place cauliflower florets in a large pan, fill with enough water so as to submerge them, add coarse Himalayan salt and bring to the boil; simmer until tender (3-5 minutes).
drain florets really well and put them back into the pan with nutmeg, 20g butter and 30g cream, stir, then blitz until smooth using an immersion blender; set aside to cool, fold in grated cheddar and leave for later.
peel and mince the garlic clove, and put it in a medium frying pan with 40g butter and anchovies; fry over medium-high heat for 1 minute.
add prawns, fine Himalayan salt, black pepper and broth granules; cook with lid on until pink (4-5 minutes), stirring a couple of times.
meanwhile, bring a small pot of water to the boil, lower eggs into it and set the timer for 6 minutes.
back to the frying pan, add mixed fish chunks, capers and 50g cream, and cook with lid on for a further 3 minutes; again, stir a little to ensure even cooking, but don't overdo it or the chunks will break up and turn to mush.
finally, add chopped parsley and leave to cool a little with lid off.
onto the eggs again; drain, peel and cut each into quarters, placing them directly into your pie dish (I used a Pyrex oval 23cm x 17cm).
using a straining ladle, scoop the fish mix over the eggs, and mix gently.
add a bit of the fish cooking liquid (30-40ml); pour the remaining liquid into a spouted jar to serve at the table (for anyone who wants a more moist pie).
spoon cauliflower mash over the fish and grill (broil) for 10-15 minutes until you see golden brown peaks on top.
serve immediately with a sprinkle of parsley leaves (optional).
