The Chard…

It all started so innocently – easy to grow and attractive with its colourful stems – you could even try and eat it if you were brave. Little did I know that it would seed itself so deeply within the compost heap that it would take over the whole veg patch and the neighbouring flower […]

But even this simple machine creates the treasured “crema”.

Getting it to this stage was pretty easy with the help of a T20 screwdriver, a Phillips screwdriver and a knife to help prise the decorative caps from the top. The steam knob prises off with a flat screwdriver, and there is a clip at the back holding the lid in place. I’ve resisted the temptation to take the boiler apart to clean it, I’m just running vinegary water through it instead. Seems to have made a difference to the water flow already!
