With only 3 ingredients you can make a tasty gel within minutes. The gel is very fragile and easily “looses” liquid, in this case whey, which is seen as a clear drop under the spoon. This loss of liquid from a gel is known as syneresis.
Some weeks ago, while doing research for Texture on gel formation in foods where no “external” hydrocolloid is added, I came across ginger milk curd (in Chinese: å§œæ±ç‚–å¥¶/è–‘æ±æ’žå¥¶). With only three ingredients – milk, ginger and sugar – it immediately caught my attention. I found a recipe and my first attempt was successful. I was amazed! With three seemingly simple ingredients I was able to form a tender, fragile gel within minutes. I loved the strong ginger taste with a touch of sweetness. After my first success I had several failed attempts, so I looked up some more recipes. What puzzled me was that, as I dug up more recipes, the different instructions were specific, but also contradictive. I couldn’t let go at this point, so I continued reading – also scientific papers. Now that I have a fairly good understanding of the science behind ginger milk curd it is clear that the many recipes I had found were full of kitchen myths. (more…)
