全世界的土壤分類依循美國的12土綱，臺灣這座小島擁有其中的11種，宛如一座自然天成的土壤博物館。我們聚焦於臺灣土壤與餅乾的轉化設計，帶大家發現臺灣的土壤多樣性。

壤壤上口的每一種餅乾，都對應著臺灣不同地區的土壤，例如加了鹽巴的鹹餅乾代表著位於臺南七股、鹽分含量較高的旱境土；加入閃亮亮、半透明糖粒的餅乾，則代表著位於臺北陽明山含有透明玻璃結晶的灰燼土。壤壤上口的土壤餅乾，象徵臺灣各地區的土壤特色，讓大家一邊享用餅乾、一邊挖掘臺灣這塊美麗的土地！

Taiwan is a wonderful island that is well known for its diverse natural resources, which contain eleven of the twelve soil types all over the world. Catchy Crust is revealing these treasures to the public, by demonstrating the different soil types with an edible medium, known as a "biscuit." The biscuits are made from flour, eggs, sugar and other seasonal ingredients. They are then used as a metaphor to introduce each type of soil seen in Taiwan, identifiable through their appearance and texture.

For instance, the biscuit with sea salt represents “Aridisol,” (a soil order in USDA soil taxonomy) which can be found in Qigu, Tainan, a district famous for salt pans and which contains a higher proportion of salt. Another example is the biscuit with shiny and translucent sugar granules. It stands for the soil type “Andisol” (a soil order in USDA soil taxonomy) that contains transparent crystals because of volcanic activities and are found in Yangmingshan National Park, Taipei. The soil biscuits made by Catchy Crust feature soil characteristics in several corners of Taiwan and enable the consumers to relish the delicacy and appreciate the beauty of this island, Taiwan.
