Basically, I do as animalmom. But, I don't use double boiler, just a stainless steel pan, being careful to stir and not scorch milk. At temp, I add vinegar, stir a few times, remove from heat and let sit 15 -35 minutes. Then strain as she does. At this point, once strained I add salt (kosher or sea salt, no iodine) and then add any seasonings. I like basil & garlic powder, oregano & sundried tomatoes, fig & lemon zest or fig & cinnamon. I don't "mold", just tighten muslin and dump into a bowl. It will be like a ball or mound of cheese. I have rolled into a log and then rolled that in herbs or nuts, depending on flavors & use...self, gift, etc. If adding herbs r dried fruits, leave the cheese moister at draining, as the dried elements will need more moisture. This cheese does not melt when cooked. When I have a lot of milk, I make this, leave it looser (less drained) as use as ricotta would be used.
Butter. Cream in a jar, shake, when you have chunks, drain, add clear water, shake, then massage with a spoon to get all water/whey out as that is what makes it rancid if left. This massaging with back of spoon can be done in a bowl easier than jar. Add salt if desired, massage it in. It's as smooth as store bought. Be sure cream is room temp, not cold. Also, if you set cream out for 10-15 hrs it will ripen, the bacteria will change the taste -- don't let it sour but, it will age. Most home butters have had cream aged to some extent. Goat butter is white, sheep butter ?
I love that you are happy will milking and the milk. But, I chuckle when you mention quantities of sheep milk -- yes, they give less than my goats (who are full sized breed). The Nigis give about what sheep do BUT I get 1 to 1.5 gal per goat per day...that's 8=11#. When I'm working 3, well there is a LOT of cheese & butter going on. I have no people to help drink. My cats, chickens & pigs (when I have them) are happy to assist.
