London Fog


A London Fog (also called an Earl Grey latte) is a hot beverage said to have originated from Vancouver, Canada. It is topped with steam milk like a latte, but is made with Earl Grey tea rather than espresso, and has vanilla syrup added to it. Earl Grey tea creates floral scents with traditional black tea notes and the addition of bergamot’s sweet citrus note. With vanilla syrup, the bitterness associated with black tea gets smoothened. The steamed milk finalizes creamy warm texture to complete the whole London fog drink.

Some of the London Fog are added to lavender, it's optional but lavender can enhance the flavor. It is also commonly made with Lady Grey tea.

A.(i) and (ii)


 * 1) (i) and (v)
 * 2) (ii) and (iii)
 * 3) (iii) and (iv)

Correct answer: C

The primary requirement that must be met by packaging material used with dehydrated foods is that there must be no transmission of water vapour from the surrounding environment into the food. Paper bags can only be used for temporary storage because it can’t prevent moisture for a long time.

Packaging should also protect against oxygen and light.Sunlight will create heat, subtly changing  teas’ flavor. Clear glass jars can’t prevent tea from being exposed to light.

So C shouldn’t be used to preserve tea.
