I’ll admit to liking strong coffee. This usually results in formation of a solid plug of compressed grounds in my cafetiere, which is always a pain to extract.
Today’s invention is a simple blade (red) which attaches to the underside of the filter, so that when the coffee is made, the blade ends up embedded in the grounds.
To make fresh coffee, rotate the plunger with blade attached. This will disrupt the plug and make it simpler to get recaffeinated rapidly.
