Our filmj\u00f6lk culture provides a mild taste with just a little tanginess and a smooth, custard-like consistency. You can also make filbunke, the elegant luxury cousin of filmj\u00f6lk, with this starter culture (recipe coming soon).<\/p>\n<p>Filmj\u00f6lk is a mesophilic product, which means that you can make it at room temperature. Each package contains a loose powder blend that is easy to measure using the included measuring spoon. And because this is a freeze-dried culture from filmj\u00f6lk with live active bacteria, you can reuse filmj\u00f6lk from your previous batch to culture your new batch for as long as you like.<\/p>\n<h3>Making Filmj\u00f6lk<\/h3>\n<p>Tools 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 pasteurized 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 tell when something clean separates from the sides of the jar as 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\u20134 hours until it sets. This depends on the ambient temperature and other conditions.<\/li>\n<li>You now have an active mesophilic filmj\u00f6lk starter, which you will use as a starter culture in the next step.<\/li>\n<\/ol>\n<p>Making filmj\u00f6lk\/filbunke:<\/p>\n<ol>\n<li>Add 50 ml (1\/4 part) of your activated culture \/ starter culture (which is the result of 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 can 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>Divide the milk between jars\/containers (e.g. 1-litre or <a href=\"https:\/\/staging.njordstorp.se\/onlinebutik\/weck-konservingsburk-glas-3-4-liter-typ-mold-med-lock\/\" rel=\"nofollow noopener\" target=\"_blank\">3\/4-litre Weck<\/a> jars work best, we think).<\/li>\n<li>Cover the jars again and leave them at room temperature for 12\u201348 hours until the filmj\u00f6lk has developed. We use <a href=\"https:\/\/staging.njordstorp.se\/onlinebutik\/snapplock-till-weckburkar-100mm\/\" rel=\"nofollow noopener\" target=\"_blank\">snap-on lids<\/a> on the Weck jars, which can be used over and over again.<\/li>\n<li>Note that the filmj\u00f6lk sets faster if your surroundings are warmer, so you should check it after 12 hours and then check every 2\u20134 hours (do this at the beginning so you build up experience) to ensure that it has set. As in the previous step, you can tell when something clean separates from the sides of the jar as 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 \u2018slimy\u2019 consistency.<\/li>\n<li>Move it to the refrigerator and store it there for at least 2 hours before eating, 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 filmj\u00f6lk (within 3 days so that the culture remains viable) or freeze filmj\u00f6lk in ice cube trays or bags as a starter for your next batch of filmj\u00f6lk.<\/li>\n<\/ol>\n<p>Njordstorp\u2019s starter culture consists of pure freeze-dried cultures without any strange ingredients. You can make batch after batch using the filmj\u00f6lk 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 with the culture you have left in the bag.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Filmj\u00f6lk Starter Culture \/ Filbunke Starter Culture<\/p>\n","protected":false},"featured_media":29749,"template":"","meta":[],"product_brand":[],"product_cat":[253,338,339],"product_tag":[290,295,309,303,311,327,346],"class_list":["post-29748","product","type-product","status-publish","has-post-thumbnail","product_cat-starter-cultures","product_cat-yoghurt","product_cat-yoghurt-making","product_tag-authentic","product_tag-curdled-milk","product_tag-probiotic","product_tag-probiotics","product_tag-starters","product_tag-vintage","product_tag-yoghurt","first","instock","taxable","shipping-taxable","purchasable","product-type-variable","has-default-attributes"],"_links":{"self":[{"href":"https:\/\/wp.njordstorp.se\/en\/wp-json\/wp\/v2\/product\/29748","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\/29749"}],"wp:attachment":[{"href":"https:\/\/wp.njordstorp.se\/en\/wp-json\/wp\/v2\/media?parent=29748"}],"wp:term":[{"taxonomy":"product_brand","embeddable":true,"href":"https:\/\/wp.njordstorp.se\/en\/wp-json\/wp\/v2\/product_brand?post=29748"},{"taxonomy":"product_cat","embeddable":true,"href":"https:\/\/wp.njordstorp.se\/en\/wp-json\/wp\/v2\/product_cat?post=29748"},{"taxonomy":"product_tag","embeddable":true,"href":"https:\/\/wp.njordstorp.se\/en\/wp-json\/wp\/v2\/product_tag?post=29748"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
