+
+## Data structure
+
+The data produced by the ingredients field type looks like this:
+
+```json
+[
+    {
+        "amount": "2 tbsp",
+        "id": "4skkkYCvbdHVhRfI5hdW7o"
+    },
+    {
+        "amount": "3 tsp",
+        "id": "2xFnDNGBloZzp59kddJBI6"
+    },
+    {
+        "amount": "200g",
+        "id": "2uqKK4iWHxhlRrGn24OLvy"
+    }
+]
+```
+
+`id` represents a relation to an entry of a collection named `"ingredients"`.
+
+`amount` is an unformatted string holding information about how much to use of the referenced ingredient.
