What is 'menma' and what does it taste like?

Menma is a common ramen topping made from fermented bamboo shoots. The bamboo shoots are dried and then fermented before being rehydrated and seasoned with a savory sauce. Menma has a slightly sweet, savory, and earthy flavor, with a satisfyingly crunchy texture. It provides a great textural contrast to the soft noodles and rich broth.
