Perhaps you're thinking of:
* Oatcakes: These were a staple food in Shetland and other parts of Scotland, made with oats, water, and salt. They were eaten plain or with butter, cheese, or other toppings.
* Bannocks: These are flat, round bread cakes made with oats, barley, or rye flour. They were also a common food in Shetland and other parts of Scotland.
It's important to note that Shetland ponies were primarily used for work purposes, like hauling peat, pulling carts, and carrying riders. They weren't bred for their use in baking or cooking.
