There are some situations where I struggle to apply cold solid butter, which is hard to spread on breads/sandwiches. I usually cut it in small pieces, put it between the pieces of bread and microwave them. How can I handle this when I do not have access to a microwave? (Even the microwave doesn't help spread the butter evenly on the entire area.)
Usually I keep it under sunlight for some time, but during early breakfast and winter this doesn't work, and it takes time as well.
How can I overcome this scenario?
