Pour the crackers into a freezer bag and grind them with a cake roll. Melt butter and mix with the cracker crumbs. Put the crumb mixture into a springform pan (22 cm Ø) and press it down to the bottom. Soak the gelatine. Stir cream cheese and vegetable stock until smooth. Season with salt, pepper and lemon juice. Squeeze the gelatine and dissolve.
Stir droplets into the cream cheese mixture. Wash the rocket, dab dry and chop 2/3 roughly. Fold into the cream cheese mixture. Place the cream cheese mixture on the cracker base and smooth it down. Chill for 2 hours. Remove the cake from the edge of the springform pan with a knife. Cover with remaining rocket and Parma ham
