I have already posted a recipe but found this cream with no eggs in it. If you are worried about health concerns. It worked very well.
170g strong coffee
190g Amaretto (170g for coffee, 20g for cream)
40 g lemon juice (I made my own mascarpone and it already had lemon juice in it)
up to 200g milk. Watch how runny your mascarpone is and add accordingly.
Mix coffee, amaretto, lemon sugar/speed 3/30 sec
Add mascarpone, milk and 20g amaretto
