Briefly about Mazu Meals Elf and Nomadic Life manga:
Suzuki Saburo is the typical isekai MC. A high school boy who started to get into cooking after getting an injury during baseball, he suddenly found himself in another world one day. With the only thing on his person being his custom knife, he wandered a desolate prairie for three days before falling unconscious.
When he woke up, he found that a nomadic tribe of elves took him in. However, there’s one big problem – the tribe has terrible cooking. Can Saburo help teach the nomadic elves the true meaning of deliciousness?
