Put the panko breadcrumbs in one breading tray and the egg and milk in the other. Mix the milk and egg with a fork.
Croquettes
Put the salmon, potatoes, wheat germ, mayonnaise, capers, spice, and lemon in a large stand mixer bowl. Mix well, and taste for seasoning.
Take a portion of the salmon mixture, slightly bigger than a tennis ball, and roll it into a football shape.
Dip the football into the egg mixture, then coat it in the breadcrumbs to thoroughly coat it.
Set it on the cooling rack, and continue with the rest of the salmon mixture until it is completely gone.
Set the cutting board in the refrigerator for at least half an hour to dry.
Put the silicon sheet on a rack of your air fryer to prevent sticking. Place the croquettes on the rack and spray them with the olive oil. Cook them for 10 minutes at 360 or until they have browned.
Notes
If you do not have true lemon packets, you might have to increase the wheat germ to make up for the amount of liquid.
