Handy Widget for Agar-Agar Clarification

I thought actually quite a few hours about the tricky parts of agar-agar clarification: the calculation of the variables: quantity of liquids, quantity of agar-agar, temperature of liquids...

And then I 'tried' to clarify pineapple juice and just made myself wrong: I wanted to clarify 0.75 liters - though then used [without valid reason] 1.5 liter juice without the adjustment of the agar - and the most stupid thing was, that I've only acknowledged my mistake, when the "to be clarified" juice was already in the ice water bath! Lame!

That is why I looked for a handy calculation widget, which I post here on my blog.
Unfortunately it was quite tough to find a proper tool.

I finally found, which is an amazing and simple tool, for just posting spreadsheets on blogs or on websites. It is not very elegant - however it works...

And with my embedded calculation, you will be able to just add the weight of the liquids and the temperatures and you will know, how much agar-agar you would need and if the temperatures are high enough.

To be able to use this tool [which is pretty simple] you need to know below points:

  • The two different liquids below are especially meant for clarification of heat sensible ingredients like juices. Either way, you can use just water for the 2nd liquid - or you can use half water, half juice for it. This 2nd liquid will be the heated liquid, which will be hydrating and dissolving the agar-agar.
  • If you would like to clarify a liquid which isn't heat sensitive, you can just use one liquid [and just put it into one cell].
  • Usually the main liquid is around 2 parts and the 2nd liquid is around 1 part.
  • To be accurate [and save] it is highly recommended to use a thermometer for the liquids and a scale for the weights.
  • The target temperature has to be above 36°C, to not prematurely jellify [which will result in a failed clarification].  To be anywhere near this target temperature you would need to keep the main liquid close to room temperature and the other liquid around the 80°C mark.
  • Please don't fill up a higher temperature than 100°C - as this is technically & physically pretty impossible. [and no - weisenheimer don't need to comment now, that anywhere below the mean sea level, water can boil at higher temperatures. This is anyway not practically].
  • Please don't even boil your liquid [just simmer], as the heat could destroy the ability of agar-agar to solidify.

Hope you can use and enjoy this little tool!

If you are editing - please have some patient - it takes few moments, until the form updates itself and shows you the agar-agar quantity, the target temperature and if it is too cold or adequate.

How to use citric acid - and why you might not want to use it anyway!

To be honest, I shied away of this topic, because I think, people can misinterpret this - big time. I don't want to be part of the problem - I want to be part of the solution!  But when Chris, over at A Bar Above  discussed this subject- I literally could not resist to join into "the discussion". Here is the video: I - however take a bit slower approach than Chris. What is citric acid? Chemical Compound Citric acid is a weak organic acid with the formula C6H8O7. It is a natural preservative/conservative and is also used to add an acidic or sour taste to foods and drinks. Wikipedia Formula: C6H8O7 Molar Mass: 192.124 g/mol Melting Point: 153C Density: 1.66 g/cm3 Boiling point: 175C Soluble in: Water Why is it controversial? In my "mixology world" it is controversial, as citric acid is the stuff, which makes the nightmarish sour mix [ preferably in powder form ] sour. Yeah - citric acid is the main ingredient in one of the most

"Monin Rocks!" - Really?

R ussell S anchez MONIN UAE MONIN Rocks @ HARD ROCK CAFE Dubai  — with   Rhiandro Gardiner  and Louie Aquias  at  Hard Rock Cafe . I have seen this on my Facebook timeline. And well... I wanted to write about Monin since quite a long time, but haven't. However this message was a catalyst, to speak up. It is already a couple of months ago, that I routinely checked the ingredient list of a Monin bottle. ...and was shocked.... Point is, that I have always defended Monin against my US colleagues as decent brand. At least with the products they offered here in the Middle East and in Europe; they came from their factory in France. Most of the ingredients [except lets say in Blue Curacao syrup] were natural. Long time ago, somebody from Monin explained, that this is due to the quite strict regulations in France for syrup - there it is a family culture to drink syrup sweetened water/seltzer. And off course especially for the k

What is the best cranberry juice in the bar?

A good friend of me "whatsapp'ed" me today and asked for my expertise: "What is the best cranberry juice?" I would loved to just let him know the brand - however it is not that easy. What do we understand of cranberry juice? One of the biggest [maybe the  biggest producer] of cranberry products is Ocean Spray. And: it is well regarded. Problem is: it is not a juice! Wait - what? Ocean Spray doesn't produce a juice - they produce a juice cocktail - which translates into a lot of water, a lot of sugar, some taste-balancers as citric acid [nothing against this really] and a minuscule portion of juice - usually around 3%. Yes they have something which is called 100% juice. Which is on one hand true, on the other the biggest deception ever. Because you don't get 100% cranberry - you get a mixture of juices of concentrate - most of the time apple and white grape and a bit of cranberry. There are also some other brands around, which might feature a h
