Anzac Day (25th April) is a national day of remembrance, commemorating all Australians and New Zealanders &#8220;who served&#8221;.<\/p>\n<p>No one is 100% sure however, how \u2018Anzac biscuits\u2019 themselves got their name. Some say that, because these biscuits travel well and don\u2019t go stale, they were made by Australian women who sent them to their men fighting the war, and that they were originally called \u201cSoldier\u2019s Biscuits\u201d. Others say that they were not named until after the war, when they were made and sold as fund-raisers for returned soldiers.<\/p>\n<p>Either way, Anzac Biscuits are as yummy as they are iconically Australian, and are fun to make at home, for Anzac Day, or at any time of year!<\/p>\n<\/div>\n<p>&nbsp;<\/p>\n<h2>To make Anzac Biscuits, you need:<\/h2>\n<p><!--more--><\/p>\n<p><img loading=\"lazy\" class=\"aligncenter size-full wp-image-4066\" src=\"https:\/\/gosciencekids.com\/wp-content\/uploads\/2015\/07\/Anzac-Biscuit-Ingredients.jpg\" alt=\"Anzac Biscuit Ingredients\" width=\"600\" height=\"420\" srcset=\"https:\/\/gosciencekids.com\/wp-content\/uploads\/2015\/07\/Anzac-Biscuit-Ingredients.jpg 600w, https:\/\/gosciencekids.com\/wp-content\/uploads\/2015\/07\/Anzac-Biscuit-Ingredients-300x210.jpg 300w, https:\/\/gosciencekids.com\/wp-content\/uploads\/2015\/07\/Anzac-Biscuit-Ingredients-150x105.jpg 150w, https:\/\/gosciencekids.com\/wp-content\/uploads\/2015\/07\/Anzac-Biscuit-Ingredients-250x175.jpg 250w\" sizes=\"(max-width: 600px) 100vw, 600px\" \/><\/p>\n<ul>\n<li><strong>1 cup traditional (old fashioned) <a href=\"https:\/\/amzn.to\/2GPQQlK\" target=\"_blank\" rel=\"nofollow noopener noreferrer\">rolled oats<\/a><\/strong><\/li>\n<li><strong>1 cup plain (all purpose) <a href=\"https:\/\/amzn.to\/2GPR6AZ\" target=\"_blank\" rel=\"nofollow noopener noreferrer\">flour<\/a><\/strong><\/li>\n<li><strong>1 cup caster (fine white baking) <a href=\"https:\/\/amzn.to\/2uepIKk\" target=\"_blank\" rel=\"nofollow noopener noreferrer\">sugar<\/a><\/strong><\/li>\n<li><strong><sup>3<\/sup>\/<sub>4<\/sub> cup desiccated (finely shredded) <strong><a href=\"https:\/\/amzn.to\/2RSaxPV\" target=\"_blank\" rel=\"nofollow noopener noreferrer\">coconut<\/a><\/strong><\/strong><\/li>\n<li><strong>125g butter<\/strong><\/li>\n<li><strong>2 tbsp <a href=\"https:\/\/amzn.to\/37V1ALg\" target=\"_blank\" rel=\"nofollow noopener noreferrer\">golden syrup<\/a><\/strong><\/li>\n<li><strong>1 tsp <a href=\"https:\/\/amzn.to\/2RRsQok\" target=\"_blank\" rel=\"nofollow noopener noreferrer\">baking soda<\/a> (sodium bicarbonate)<\/strong><\/li>\n<li><strong>2 tbsp hot water<\/strong><\/li>\n<\/ul>\n<p>Our supplies are all Australian brands, purchased from local grocery stores.

I like to think this makes slightly healthier biscuits, and they taste just as good.<\/p>\n<p>Golden syrup is an common pantry ingredient in Australian households, but it may be harder to find in some parts of the world. It\u2019s made from sugar cane, so it\u2019s not the same as corn syrup or maple syrup. You might find it with the pancake ingredients or in the baking ingredients aisle.

Depending on where you live, it may also be called baking soda, bicarbonate of soda, bicarb, bread soda or cooking soda. Note: it is not the same thing as baking powder. (Baking powder is not the same. It&#8217;s a mixture of both baking soda and cream of tartar, just FYI.)<\/p>\n<p><img loading=\"lazy\" class=\"aligncenter size-full wp-image-4064\" src=\"https:\/\/gosciencekids.com\/wp-content\/uploads\/2015\/07\/Edible-Fizzy-Science-with-Anzac-Biscuits-fun-and-yum-for-toddlers-and-up-1.jpg\" alt=\"Edible Fizzy Science with Anzac Biscuits - fun and yum for toddlers and up\" width=\"600\" height=\"1040\" srcset=\"https:\/\/gosciencekids.com\/wp-content\/uploads\/2015\/07\/Edible-Fizzy-Science-with-Anzac-Biscuits-fun-and-yum-for-toddlers-and-up-1.jpg 600w, https:\/\/gosciencekids.com\/wp-content\/uploads\/2015\/07\/Edible-Fizzy-Science-with-Anzac-Biscuits-fun-and-yum-for-toddlers-and-up-1-173x300.jpg 173w, https:\/\/gosciencekids.com\/wp-content\/uploads\/2015\/07\/Edible-Fizzy-Science-with-Anzac-Biscuits-fun-and-yum-for-toddlers-and-up-1-519x900.jpg 519w, https:\/\/gosciencekids.com\/wp-content\/uploads\/2015\/07\/Edible-Fizzy-Science-with-Anzac-Biscuits-fun-and-yum-for-toddlers-and-up-1-87x150.jpg 87w, https:\/\/gosciencekids.com\/wp-content\/uploads\/2015\/07\/Edible-Fizzy-Science-with-Anzac-Biscuits-fun-and-yum-for-toddlers-and-up-1-250x433.jpg 250w\" sizes=\"(max-width: 600px) 100vw, 600px\" \/><\/p>\n<h2>What to do<\/h2>\n<p><strong>1.

Citrus juice, buttermilk, molasses, honey, vinegar and chocolate are all acidic. So is the golden syrup that we use in our recipe. When baking soda mixes with the melted butter \/ golden syrup mixture, a chemical reaction occurs forming an unstable carbonic acid, which breaks down into carbon dioxide (CO<sub>2<\/sub>). Carbon dioxide is a gas &#8211; the same gas that makes fizzy drinks all fizzy &#8211; and this is what causes our mixture to froth up and appear to grow in size. Heat speeds up the reaction.<\/p>\n<\/div>\n<div class=\"info-box\">\n<h3 class=\"warning\">Please note&#8230;<\/h3>\n<p>Mixing together pantry ingredients is a safe and fun way to explore chemical reactions with kids. The ingredients used here are all generally taste-safe, except for the sodium bicarbonate in it&#8217;s concentrated form. (It&#8217;s OK once it&#8217;s mixed with the other ingredients).<\/p>\n<p>This recipe contains gluten and dairy which are common allergens.<\/p>\n<p>As always, be very careful with kids around hot stove tops, gas flames, when handling boiling hot ingredients and using the oven.<\/p>\n<p>All kids&#8217; activities on this blog require attentive adult supervision.
