They would bring their home-prepared dough to the bakery in baking tins and would pay the baker for baking it. The reason for this is that town houses were fitted with iron ovens attached to kitchen ranges which were not regarded as 'good bakers of bread'. The Derwen Bakehouse was one of three such bakeries in Aberystwyth. It served the local community from around 1900 to 1924 and was re-erected in the National Museum of History during the mid-1980s.

Trifle and rice pudding remain very popular in west Wales, with Freeman commenting that trifle is the "more or less obligatory 'finale' to a special occasion feast". In the case of rice pudding, this is expected to be rich and creamy.
