Following a method invented by Professor Justus von Liebig in the mid-19th century, 30kg of prime beef is used to make 1kg of Liebig Meat Extract. Containing no fat or additives, it is perfectly suited to refining sauces, soups, meat & vegetable dishes. Half a teaspoon for 1 litre of soup or broth. Made from Argentinian beef. The German postal service recently dedicated a stamp to Justus von Liebig, whom we have to thank for the Meat Extract – & the countryside has to thank for inorganic fertiliser, to mark his 200th anniversary. 40 g jar. Gluten-free.
