The yoghurt probably originated sometime between the 1200s and 1800s from what we called filbunke.<\/p>\n<p>Filbunke starter culture is a <strong>mesophilic<\/strong> starter that can be made at room temperature &#8211; no yoghurt maker is needed.<\/p>\n<p>Contents: milk powder, starter cultures (active microorganisms, lactic acid cultures including Lactobacillus Bulgaricus, Lactobacillus Kefir, Streptococcus Thermophilus, Lactobacillus Casei and Lactococcus Helveticus)<\/p>\n<p>This product is freeze-dried and can be stored for a long time. The package can be resealed after opening and therefore also used for several batches.<\/p>\n<p>Njordstorp&#8217;s starter cultures are pure, freeze-dried cultures without any strange ingredients. You can produce batch after batch using the filbunke you made the first time. Depending on your hygiene, it may become contaminated, and if you notice that the taste or acidity changes, you can start over using the culture remaining in the pouch.<\/p>\n<p>Storage instructions for starter culture:<br \/>\nStore in the refrigerator or freezer. Starter culture is highly hydrophilic; if moisture enters the package, it will reduce the quality. The shelf life is at least 2 years in the freezer.<\/p>\n<h3>Making Filbunke \/ Making Viili<\/h3>\n<p>You need:<\/p>\n<ul>\n<li>Jars<\/li>\n<\/ul>\n<p>Activating your starter:<\/p>\n<ol>\n<li>Heat one cup (200 ml) of milk to 24\u00b0C. If you use raw or unpasteurised milk, boil it and let it cool to 24\u00b0C.<\/li>\n<li>Add the culture to the milk and stir until it has dissolved. Please do not whisk, as this creates air bubbles in the milk that slow down incubation.<\/li>\n<li>Cover the jar with a cloth to keep the milk free from dust and airborne particles.<\/li>\n<li>Let the milk sit for approximately 24 hours and then check whether it has set. You can see this when something clear separates from the sides of the jar when you tilt it. Some mesophilic yoghurts may look messy, but you will clearly notice that a change in consistency has occurred.<\/li>\n<li>If it has not set within 24 hours, let it stand for an additional 2-4 hours until it sets. This may depend on the ambient temperature and other conditions.<\/li>\n<li>You now have an active mesophilic yoghurt starter, which you will use as a starter culture in the next step.<\/li>\n<\/ol>\n<p>Making filbunke\/viili:<\/p>\n<ol>\n<li>Add 50 ml (1\/4 part) of your activated culture \/ starter culture (which is the result from the previous step) to 1 litre (up to 4 litres if you use it all) of milk. Do this in a single container so that the entire starter culture can be mixed evenly with all the milk. The milk may be at room temperature or straight from the refrigerator.<\/li>\n<li>Stir gently until the active starter culture has completely dissolved. Please do not whisk, as this creates air bubbles in the milk that slow down incubation.<\/li>\n<li>Distribute the milk into jars\/containers (for example, 1 l or <a href=\"\/onlinebutik\/weck-konservingsburk-glas-3-4-liter-typ-mold-med-lock\/\">3\/4 l Weck<\/a> jars work best, in our opinion).<\/li>\n<li>Cover the jars again and leave them at room temperature for 12-48 hours until the yoghurt has set. We use <a href=\"\/onlinebutik\/snapplock-till-weckburkar-100mm\/\">snap lids<\/a> on the Weck jars, which can be used again and again.<\/li>\n<li>Note that filbunke sets faster if your surroundings are warmer, so you should check it after 12 hours and then check every 2-4 hours (do this at first so you build up experience) to ensure that it has set. As in the previous step, you can see this when something clear separates from the sides of the jar when you tilt it.<\/li>\n<li>Some mesophilic yoghurts may look messy, but you will clearly notice a change in consistency. Keep in mind that mesophilic yoghurt is naturally thinner than thermophilic yoghurt, so be prepared for a viscous or more &#8216;slimy&#8217; consistency.<\/li>\n<li>Move it to the refrigerator and store it there for at least 2 hours before eating it, as this will help it thicken and improve its flavour.<\/li>\n<li>You can use a spoonful of the previous batch to make more filbunke \/ viili (within 3 days so that the culture remains viable), or freeze the filbunke\/viili in ice cube trays or bags as a starter for your next batch of yoghurt.<\/li>\n<\/ol>\n","protected":false},"excerpt":{"rendered":"<p>Filbunke starter culture is sometimes called Viili starter culture or L\u00e5ngfil starter culture and is a mild yoghurt characterised by a viscous, gel-like and ropy texture.<\/p>\n","protected":false},"featured_media":29935,"template":"","meta":[],"product_brand":[],"product_cat":[253,338,339],"product_tag":[290,309,303,311,342,343,327,346],"class_list":["post-29934","product","type-product","status-publish","has-post-thumbnail","product_cat-starter-cultures","product_cat-yoghurt","product_cat-yoghurt-making","product_tag-authentic","product_tag-probiotic","product_tag-probiotics","product_tag-starters","product_tag-viili","product_tag-viili-starter-culture","product_tag-vintage","product_tag-yoghurt","first","instock","taxable","shipping-taxable","purchasable","product-type-variable"],"_links":{"self":[{"href":"https:\/\/wp.njordstorp.se\/en\/wp-json\/wp\/v2\/product\/29934","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/wp.njordstorp.se\/en\/wp-json\/wp\/v2\/product"}],"about":[{"href":"https:\/\/wp.njordstorp.se\/en\/wp-json\/wp\/v2\/types\/product"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/wp.njordstorp.se\/en\/wp-json\/wp\/v2\/media\/29935"}],"wp:attachment":[{"href":"https:\/\/wp.njordstorp.se\/en\/wp-json\/wp\/v2\/media?parent=29934"}],"wp:term":[{"taxonomy":"product_brand","embeddable":true,"href":"https:\/\/wp.njordstorp.se\/en\/wp-json\/wp\/v2\/product_brand?post=29934"},{"taxonomy":"product_cat","embeddable":true,"href":"https:\/\/wp.njordstorp.se\/en\/wp-json\/wp\/v2\/product_cat?post=29934"},{"taxonomy":"product_tag","embeddable":true,"href":"https:\/\/wp.njordstorp.se\/en\/wp-json\/wp\/v2\/product_tag?post=29934"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
