New improved L Reuteri yogurt method
Improve the texture with one extra step!
Mastering Dr William Davis’s homemade yogurt made with the probiotic ‘Lactobacillus Reuteri’ has been no easy feat. We empathise with your failed attempts because we’ve had plenty along the way too. No one really wants to eat thin and separated yogurt, do they? As we always do, the Luvele kitchen has continued to experiment and we have now discovered a key step that makes all the difference.
IT’S ALL IN THE MILK
Dr Davis created his method using half and half milk, which is a full-fat milk commonly available in America (in the UK and Europe, it’s known as ‘half cream’). Half and half is a blend of equal parts whole milk and light cream. If half and half milk is available in your area, we recommend you follow Dr Davis original method. From our feedback, this method produces reliable results. If half-and-half milk is not available in your country, choose organic milk, that is free of pesticides, hormones, antibiotics, fertilisers and GMOs and follow the next step.
HEATING THE MILK
Traditional yogurt making practises have always heated the milk first. Heating and holding milk at 82° C (180° F) for 20 minutes (or longer) denatures the milk proteins so that they bind and set together. In addition to this, the little bit of evaporation and concentration that occurs during the extended heating helps to improve the texture.
Including this step before adding the probiotic bacteria and prebiotic powder made a profound difference to the structure and texture of our L. reuteri yogurt. Without heating, our first attempts with homemade half and half milk produced fragile and thin yogurt with lots of separated whey.
FEWER PROBIOTIC TABLETS (OPTIONAL)
Dr Davis’s original method specified 10 probiotic(BioGaia Gastrus) tablets be used to inoculate milk into yogurt. If you’re familiar with BioGaia Gastrus probiotic tablets, you’ll know how expensive they are! We have experimented using fewer tablets and are pleased to say that we had significant results with only 3 tablets per litre of milk. Because our experiments produced thick textured, tart tasting yogurt we are confident that bacterial fermentation occurred, however without clinical trials, accurate CFU counts are unknown.
CONSISTENCY
Despite heating the milk, it’s still not unusual for the first batch to have the consistency of drinking yogurt or turn out separated. Both are perfectly consumable. A separated jar contains the same quantity of beneficial bacteria as a non-separated jar. The L. Reuteri are present in both the solids (curds) and the translucent liquid (whey), and therefore both should be consumed. You can either stir the whey into the curd for a thin yogurt or strain it off. Whey is highly nutritious and can be used in a variety of health-giving ways. Adding it into smoothies is a delicious way to get a probiotic boost. For more creative ideas refer to this post. Subsequent batches will be thicker.
SEEDING THE NEXT BATCH
A portion of your first jar of L. reuteri yogurt – the ‘mother batch’ - can then be used to re-inoculate your next jar of L.reuteri yogurt. This means that when preparing your next batch, you simply replace the 3 (or more) crushed tablets with a third a cup of L. reuteri yogurt. It is also possible to freeze a portion of yogurt or whey and use at a later time.
To ensure the L reuteri strains stay pure and uncontaminated, we recommend re-inoculation not occur indefinitely. To ensure the yogurt stays abundant with the L. reuteri strains, and not a breeding ground for other, unwanted bacteria, we recommend starting a fresh mother batch after 4-5 re-inoculations. If you notice any significant changes to the texture, smell or taste of your yogurt, you should do this sooner.
To keep the strains in abundance, some customers suggest adding 1 crushed probiotic tablet with the third of a cup L. reuteri yogurt or whey.
Quantity: The recipe below makes 1 litre of yogurt. Double the ingredients to fill the capacity of the Luvele yogurt maker jar.
DISCLAIMER
Luvele’s L Reuteri Yogurt Disclaimer: The team at Luvele are learning that making L Reuteri yogurt is still very experimental. Dr Davis who first came up with the idea of L Reuteri yogurt, himself has changed his recipe a number of times to try to create a more consistent outcome. However, may people still struggle with inconsistent results.
Please understand, at the end of the day, the L reuteri probiotic DOES NOT make yogurt, traditional yogurt that is, you can only try to make a yogurt like product.
Also note; we have spoken directly with BioGaia in Sweden who are the manufactures of the L Reuteri probiotic, and they themselves strongly point out that L Reuteri was not designed or developed for making yogurt.
It is our belief at Luvele that the combination of ingredients in BioGaia’s L Reuteri probiotic are not always equal from tablet to tablet. It is possible they contribute to the unreliability / inconsistent results. Making yogurt with the L Reuteri strain is unquestionably trying to get the tablets to do something they were never designed to do.
Therefore, this it really a food hacking exercise that can result in inconsistent outcomes.
