I have two coffee machines that produce crema when brewing coffee. One is the Krups KP1010 Home Cafe Single Serve Coffee Machine.
The other is the Senseo 7810 Single-Serve Gourmet Coffee Machine.
They both use coffee pods and they are both discontinued, but Senseo still makes and sells the pods and a few companies still have one or two Senseos available at ridiculous prices from $200.00 to $400.00 American. I bought mine for $15.00 from Senseo on close-out. I wish I had purchased two.
If you really want one of either of those machines you can check out the thrift stores.
