According to the British "Daily Mail" report, this is the world's first on-board decompression recipe, including black echinacea and licorice ice cream distributed after boarding, Japanese matcha and lavender rice cakes distributed after taking off, chamomile tea with fennel and lemon vanilla distributed during flight, mushrooms and tomato powder nut sticks distributed before landing, and so on. These foods can help people "calm down, eliminate internal heat", replenish energy and "awaken" the senses.

As for making the ice cream black, Professor Spencer said that it was to give passengers a "small surprise" and distract them from the messy boarding scene. "When traveling, people are always in a hurry, and it is inevitable that there will be pressure. Eating well is often' Monday morning quarterback' ... I cooperated with Monarch Airlines and used these foods to bring you a real' Happy Package' to let passengers enter the holiday mode as soon as possible. "

At present, this cookbook is still in the testing stage and is only available free of charge on two designated routes in Europe.
