Strawberry Jam Making

Making your own jam at home? Learning how to test for the setting point is key to achieving the perfect texture — not too runny, not too firm. Here’s how to do it with or without a thermometer.**

自家製果醬,最難掌握的其實不是風味,而是「凝固點」!太稀會變成果醬汁、太稠又像膏狀。今天就來教你兩種簡單測試方法,讓你每次煮果醬都剛剛好。

Method 1: Cold Plate Test(凍碟/凍匙測試法)

Cold Plate Test for Jam Making

1. Chill a small plate in the fridge for at least 5–10 minutes.
先將平碟放入雪櫃,冷藏 5–10 分鐘。

2. When you think the jam is nearly ready, drop a small spoonful onto the cold plate.
果醬煮至接近完成時,滴少量果醬在冷凍平碟上,靜待片刻。

3. Push with your finger — if wrinkles form on the surface or the jam holds its shape,
it’s done!
用手指輕推邊緣,若表面出現皺摺、或果醬有微微凝結感,就是「凝固點」。

4. If not, return to the heat and test again after 5 minutes.
若仍未凝固,可繼續煮 5 分鐘,再次測試。

Method 2: Thermometer Test(溫度計測試法)

Don’t want to guess? Use a sugar or jam thermometer.

* When the mixture reaches 105°C (221°F), it has hit the setting point.
* Make sure to stir occasionally to avoid burning the bottom.

不想靠直覺?那就用果醬溫度計吧!當溫度達至 105°C 時,就是理想的果醬凝固點。

Yves Tips~

Using high-pectin fruits (like apples or citrus) makes it easier to reach setting point naturally. Low-pectin fruits may need added lemon juice or pectin.
使用高果膠水果(例如蘋果或柑橘類)可自然較易達到凝固點;而低果膠水果則可能需要加入檸檬汁或果膠協助凝固。

Another useful trick: pair low-pectin fruits with high-pectin ones to help balance the texture. 另一個實用小技巧:也可以將低果膠水果與高果膠水果搭配煮成果醬,以提升凝固效果與口感平衡。

Unexpectedly found a bowl of KL comfort food on Ca Unexpectedly found a bowl of KL comfort food on Castle Street market.
Even better — it’s run by Malaysians and Hong Kong people.

The crispy pork belly was SO good.
Crunchy on the outside, but soft, juicy and full of flavour inside.

The broth had real depth, rich without being heavy, and the prawns were fresh with that perfect bouncy bite.

Ended up standing there finishing every drop of soup 😂 
Definitely one of those “I’ll be back again” pop-up food booth. Vegetarian menu is also available 👍

Soft-boiled duck eggs are very popular in Thailand Soft-boiled duck eggs are very popular in Thailand — you’ll find them everywhere, from street food stalls to noodle shops and restaurants.

Thai people love the soft-boiled texture: a tender egg white with a yolk that’s just set, rich, and still beautifully orange.
It’s often eaten with lots of garlic and fresh chillies, making it even more flavourful.

If you prefer, you can cook it fully done — just adjust the timing to your liking.

🥚 Soft-boiled: about 5–6 minutes
🥚 Fully cooked: about 6–8 minutes

泰國人好鍾意食鴨蛋,無論路邊攤、粉麵店,定係餐廳,都隨處可見。

佢哋特別鍾意半熟嘅口感:
蛋白嫩滑,蛋黃剛剛熟,仲保持住鮮艷橙色。

通常會配大量蒜頭同辣椒一齊食,簡單但非常惹味。

如果唔食半熟,其實都可以煮至全熟,按自己喜好調整時間就可以。

🥚 半熟:約 5–6分鐘
🥚 全熟:約 6–8分鐘

A kumquat marmalade,
sent to the Dalemain World Marmalade Awards in the UK —
simply as it is.

They didn’t know about Yves Kitchen,
and didn’t know who I was.

It was just a jar.

And it came back with a Silver Award.

Flavour: 10/10
Total: 18/20

For me, this means more than I expected.
Because it feels like being seen —
purely through taste.

This Kumquat Marmalade is for my grandpa. I hope this made him proud xx
