Scientists say the most dunkable biscuit for your cup of tea is a Hobnob.
The oat biscuit came out ahead of digestives, rich tea and shortbread.
The British Medical Journal reports that oat biscuits have the best 'structural integrity'- meaning they're less likely to quickly fall apart after dunking.
The study aimed to identify the best accompanying biscuit for nutritional content, crunchiness, and integrity when dunking.
The study, which was carried out by hospital staff, also took into account the time required to achieve the optimal temperature of a cup of tea without risk of harm (oral scalding) using the resources available in a standard hospital staff room.
Biscuits were dunked into the hot drink 30 seconds after brewing and again after 60 seconds.

In the study titled, 'Direct Uptake of Nutrition and Caffeine Study (DUNCS): biscuit-based comparative study' researchers considered four different varieties of round, non-chocolate biscuits: oat, digestive, rich tea, and shortbread.
A standardised cup of tea was determined on the basis of colour and taste using normal tea-making methods.
