source: Acquired taste
text: Acquired taste An acquired taste is an appreciation for something unlikely to be enjoyed by a person who has not had substantial exposure to it. In the case of food and drink, this may be due to a strong odor (such as stinky tofu, Gefilte fish, durian, hákarl, black salt, nattō, stinking toe, asafoetida, surströmming, or certain types of cheese), taste (alcoholic beverages, Vegemite or Marmite, bitter teas, salty liquorice, malt bread, unsweetened chocolate, sushi, garnatálg), or appearance. Acquired taste may also refer to aesthetic tastes, such as taste in music, other forms of art, or in beauty.

text: Peter Hardwick Peter Hardwick (born 1958) is an Australian food horticulturist and environmentalist, recognized as an early pioneer of the Australian bushfood industry. He publicly challenged the established belief that native Australian food plants were not suitable for cropping; conceived the commercial strategy of processing strong flavored native food plants; and, developed the use of wild and seedling genetic diversity to overcome the lack of domesticated varieties previously considered a limitation with Australian native food plants.

source: Salty liquorice
text: Salty liquorice Salty liquorice, also known as salmiak or salmiakki (in Finland), is a variety of liquorice flavoured with ammonium chloride, common in the Nordic countries, the Netherlands, and northern Germany. Ammonium chloride gives salty liquorice an astringent, salty taste (hence the name), which has been described as "tongue-numbing" and "almost-stinging". Salty liquorice is an acquired taste and people not familiar with ammonium chloride might find the taste physically overwhelming and unlikeable. Salty liquorice candies are almost always black or very dark brown and can range from very soft to very hard and may be brittle. The other colours used are white and variants of grey. Salty liquorice is also used as a flavouring in other products, such as ice creams and alcoholic beverages.
