    Buttermilk Starter


    "Buttermilk!!! "

    When I moved from Germany to Italy more than 20 years ago one of the things I was missing was buttermilk. I'm so glad I found out about CulturesForHealth, because now I can have buttermilk every day, I decide the quality of the milk, I decide how much I make. And the TASTE is absolutely awesome!!! Thank you so much!

    "Best Buttermilk Culture!!"

    New to dairy cultures - easy and great results.

    "Re-using the culture works"

    I'm new to dairy culturing so not much to comment. This product is presented as having the capacity to propagate, and having made 4 or 5 successive cultures using raw milk and using the former batch to activate, it is still making buttermilk. Response from CFH: This is great to hear! The Heirloom Buttermilk is an organism that will self-perpetuate so long as the conditions are right and it never accidentally gets contaminated. We are glad to hear it is working with raw milk as the mother batches, as that is not normal. We do recommend pasteurizing at least the milk used for the mother, and then using her for the raw milk buttermilk (as in never heating it at all). Keep on buttermilking!

    "Buttermilk Bread"

    Buttermilk makes rich delicious bread. A challenge at high altitude, 6000 feet. I use sourdough starter with the buttermilk and the dough cycle in my bread maker. Crispy crust with a soft center.

    "Easy to Make"

    This is my first try at making buttermilk. I was making milk kefir prior to purchasing this product, but it got to be too time consuming. Now i just add a little saved buttermilk to a fresh quart of milk and it's done in a few hours time. I love the ease taste of this buttermilk. I drink about 1/2 cup daily.

    Sour Cream Starter Culture


    "Great sour cream!"

    I really thought my first attempt would be a flub (I had trouble keeping the temp low enough while the cream was on the stove), but the sour cream turned out fabulously! I used it in a cheesecake and as a topping on lots of foods. It turned out nice and thick. Can't wait to make more!

    "Brown and caked starter culture"

    I bought the sour cream starter in April. It was brown and caked and did not make sour cream. I then talked to CfH and they said they would replace it without charge, which they did. However, it was from the same batch of bad starter, brown and caked. So they knowingly will sell a batch that is not active then replace it with the same bad batch. Response from CFH: We are terribly sorry for your experience, as that is not common. We have reached out to you via email and look forward to a solution, as we would like to ensure satisfaction.

    "This made delicious raw cream sour cream!!"

    well worth the minimal effort to make raw cream sour cream

    "Excellent product. "

    Excellent product. I didn't think it was going to set up at first. It was close to the final hour and it was still looking like milk. In an hour after I checked again, it finally set up. It was the best sour cream I have ever had.

    "Love it!!"

    I use the Kefir and mild yogurt cultures and LOVE them, so I tried the sour cream. It was a little more work, but it is REALLY GOOD!! I like an organic product without all the additives, and this came out thick and yummy...so why do they add stuff to it commercially??? This stuff is great !! and lasts a long time in the frig!!

    Crème Fraiche Starter Culture


    "I made delicious mistake "

    I bought to make creme Fraiche, bought a half gallon of raw milk from Old Ford Farm, one of the few places to legally purchase it in NY. The weather was unseasonably cold so I used a seedling mat, I panicked when I saw, packaged up, brought to show the owner of the farm, Becky. She told me not to panic, told me that I made cheese, so I had to season it. I was going to leave it for her to see if salvageable, and she said that I had raw fermented dairy, to keep it. It took about 3 weeks to have seasoning perfect but after 3 months is still good. May not have done what I expected since I over heated a bit but was a great surprise. I also pickled onions with the same starter and am going to keep trying new things. I haven't tried creame Fraiche again yet, but I will. Awesome product

    "Sadly, it doesn't work for me"

    i have tried 3 times to make this product work and sadly i've had barely an improvement in the consistency of the milk. the last batch was done over the weekend with fresh raw milk in the hopes that supermarket milk was the problem. i mixed equal parts of cream and whole milk and i would have had better results if i had just whipped it by hand until peaks formed. the only upside is that i'm only out $7 and the cost of milk. i won't bother making the 4th packet. Response from CFH: We are sorry for your experience. We thank you for troubleshooting with us via email, and hope future attempts have worked out to be yummy!

    "Excellent creme fraiche"

    I have made creme fraiche with a few other cultures and this is by far the best. It thickens relatively quickly and is the least "sour" tasting - it tastes almost buttery. Its better than what I can get already made in the store. I put it in the oven with the light bulb on to thicken it and that works great.

    "Success The Second Time Around"

    I purchased CF culture a while back and wondered why the big deal was. I was not impressed with my results. CFH reached out to me and gave me advice. So glad! I followed their instructions to the T and was pleased with my creme fraiche. My whole family loved it. The trick is keeping the temp around 72. I used my electrical heating pad. Worked! Thank you, CFH!

    Worked perfectly, possibly because I used a thermometer, and used cream that was pasteurized only (not ultra-pasteurized nor UHT [ultra high temperature] treated). Slight whey separation, not a problem. Mildly sour, with subtle other tastes. Delicious on slow cooker oatmeal made with steel cut oats, apples, cinnamon, nutmeg, and almond milk. Will now start experimenting to see how well this will work with nonfat milk products. Kudos to cfh for making this available.

    "Great product!"

    Creme fraiche is easy to make and I add it to soups and vegetables. Sometimes I eat it right off the spoon, which is great. To make it, I use 1 pint of organic half and half and it tastes wonderful. :)
