Why do some biscuits take longer to completely soak if completely covered by liquids instead of slowly dunked?
When you dunk the biscuit, the tea replaces the air inside the biscuit. The air has to be able to escape the biscuit for this to happen. This is easy if part of the biscuit is still dry, because the surface is porous.
The Short Answer
When you dunk the biscuit, the tea replaces the air inside the biscuit. The air has to be able to escape the biscuit for this to happen. This is easy if part of the biscuit is still dry, because the surface is porous. But when you completely dunk the biscuit the porous surface is covered by tea, which resists the passage of air. Try putting a handkerchief up top your lips and blowing through it. Then try it with a sopping wet handkerchief, and you'll see the difference.
