Mix the eggs, gram flour, milk, herbs, baking powder together in a blender. The Add the cayenne pepper and 1 tsp of oil. Blend. Add the salmon and pulse for a few seconds. The batter should be thick, textured and pourable.
If you have time rest the batter for 20-30 minutes.
Using the other remaining oil grease a pancake pan and put it medium heat. When the pan is hot add dollops of the batter. let them spread out a bit into circular shapes ( you can use silicon moulds if you have any).
After a minute or so, when the surface has set, turn them over and cook for 30-25 seconds or until golden brown. Transfer them to a plate and make more blinis using up the batter.
Serve at room temperature with salad or toppings and dips of your choice.
