PS: The 'sweetened condensed milk' in those recipes goes under the brand name 'Carnation' in the UK. (Make sure you pick up the 'condensed' milk, not the 'evaporated' type).
You're looking for Carnation CONDENSED Milk. (It's got sugar in it. Avoid Carnation Evaporated Milk and Carnation Light Condensed Milk - The former hasn't got sugar. The latter isn't creamy enough).
thanks that has cleared that up. you wouldnt like to be an elf and sit on my computer desk you pop up everywhere with answers. good to have you and lots more around on this ab. thanks
