Top and tail the gooseberries. In a medium-sized pot bring to the boil the water, lemon juice and caster sugar.
Turn down to a low simmer and add the gooseberries. Simmer for 30 minutes (do not touch or stir the liquid to keep it clear, you don’t want to break the gooseberries). Take the pot off the heat and cling-film the pot to infuse the flavour.
Leave to cool. Carefully strain the liquid from the gooseberries through a sieve and muslin cloth, keeping the berries and the liquid separate.
For the jelly
Put 150ml of the gooseberry liquid into a pot with ½ tsp of agar agar. Bring to the boil, stirring constantly. Once boiled, pour through a fine sieve into a shallow tray. Leave to set. Once set, cut into 1cm cubes.
For the reduction
Put the remaining liquid into a pot and gently simmer until reduced to a syrup-like consistency. Leave to cool.
For the purée
Place the cooked gooseberries into a food processor and blend until smooth. Pass through a fine sieve.
For the crackling powder
Using a sharp knife make approximately ½cm spaced
cuts on the top side of the pork skin, horizontally and vertically, being careful not to cut right through. Sprinkle with salt and vegetable oil and rub in with your hands. Roast in the oven at 160C/Gas Mark 3 for approximately 1 hour or until the skin has puffed up and crisped.
Once cool, put in a food processor and blend until smooth (it will end up like a paste). Spread out evenly on a paper towel. Keep changing the paper to draw out the fat and dry it out.
For the grissini
Sieve the flour into a bowl. In a pot add butter, water, olive oil and salt. Place somewhere warm and heat to 37C. Add yeast. Add the wet mixture into the flour and knead with your hands until it forms a firm dough.
Cling-film the bowl and leave to prove for 2 hours. Once proved, roll out the dough to approximately 2mm thickness. Then cut into a 30 x 30cm square discarding the excess. Brush the rolled-out dough with egg white and sprinkle it evenly with the crackling powder. Cut into 2mm strips. Place on a baking tray and bake at 170C/Gas Mark 3 for 5 minutes.
To serve (optional)
If you have a metal cone or cylinder, make a spiral by carefully wrapping the grissini around it and bake as above. Garnish the pork with the gooseberry jelly dice and spots of reduction and purée.
