Felice Tocchini has created a biscuit which he claims can survive up to a minute in a hot drink before disintegrating into a sodden mess. This smashes the current record of 25.5 seconds for a chocolate digestive.
Crunch time: Felice Tocchini believes his dunking biscuit will last for a minute before disintegrating. He spent three weeks testing hundreds of different ingredients to create his chocolate and vanilla-flavoured masterpiece.
The recipe is a closely-guarded secret, but he revealed that the key was layering flour and oat-based doughs to build strength, before coating it all in an 'impermeable' egg-based glaze before baking.
One of the more outlandish ingredients is tiny slivers of sweet potato, which keep it together without spoiling the taste.
