Easy homemade blinis

These are maybe a bit more like mini savoury pancakes, but can be made with store cupboard essentials and are delicious, cheap and easy to do. Great with seafood, like crayfish in garlic mayonnaise, smoked salmon with cream cheese and prawns in marie rose sauce for example, andf of course caviar if you are feeling flush! A lovely wee anytime snack.
These freeze well too, so you can cook a batch and keep some for another occasion.
