If I have cake or puddings they have to be low carb, as the amount of sweetening in a 'normal' one would be overpowering for me.
I can happily eat an icecream made with cream and eggs, or a trifle made with real custard, cream, no sugar jelly or even gelatin, usually with yogurt of some kind mixed in and then whisked just as it gets to room temperature so it is all frothy - sometimes I mix in some berries before the whisking to colour it, and then more afterwards, and sometimes I make almond sponge biscuits to put into it, soaked in rum or brandy for special occasions.
There seems to be the illusion that the low carb diet is somehow second best - but when I take my food out to a social gathering I know how fast it vanishes, or I do now, having found only my empty dishes by the time I got to the table. They always seem to be the first ones washed up.
