Lemon Basil - Bai Maeng-lak (ใบแมงลัก)

>> Sunday, August 14, 2011


I know I just complained to you in a recent post on Thai spicy basil stir-fry about the scarcity of holy basil (Bai Ka-prao ใบกะเพรา) outside Asia (which has led to all the faux Pad Ka-Praos on the menus of several Thai restaurants in Europe and North America). But may I please have your permission to whine a little more?

It's so hard to find lemon basil. And nothing can be used in its place. Nothing.

To make matters worse, lemon basil has ridiculously short shelf life. By the time, you discover that some fresh lemon basil has made a rare appearance at your favorite Asian store, it's already half dead.

So it's unfortunate that lemon basil (Bai Maeng-lak ใบแมงลัก) happens to be an indispensable ingredient/garnish in two of my favorite Thai dishes, namely rice noodles with curried coconut-fish sauce (Khanom Jin Nam-ya ขนมจีนน้ำยา) and spicy mixed vegetable soup (Kaeng Liang แกงเลียง). And while holy basil and sweet basil can be interchangeably used in some cases (it is not ideal, but it doesn't precipitate the end of the world either) no other kinds of basil can be used in lieu of the unique, citrusy lemon basil. The two aforementioned dishes, for example, become sad and depressing -- the latter especially -- in the absence of this herb.

Fortunately, just as you can grow your own cilantro in order to harvest the roots, you can also grow your own lemon basil. Lemon basil can be grown from seed easily, grows fast, and is low-maintenance; the seeds can also be found easily in the US. It can also be grown indoors provided that you give it enough sunlight daily.

The easiest way to plant lemon basil that I know of is to fill a wide pot (with drainage holes) with top soil about 3/4 of the way. Then scatter the seeds on the surface of the soil (leaving about 4-5 inches between them) and moisten the soil lightly. The seeds should sprout in 7-10 days.

With some sunlight and adequate water, your lemon basil should be ready for harvest around 30 days after the seeds have sprouted. The plants should produce new leaves for you to harvest every week thereafter. Some fertilizer once a month should be adequate (highly recommended especially if you grow lemon basil indoors).

Unfortunately, it's also not that readily available in Thailand - at least here in Ayutthaya. Neither Big C nor Tesco-Lotus stocks it.

I have a TON of lemon basil, and apart from using it in chimichurri (in lieu of the lemon zest/juice), I'm at a loss as to what to do with it! Any recipes for the above, or any other ideas?

Thanks!

apostcard - Seriously!? Oh, my.

sundevilpeg - Great idea! I've always wondered about the different ways people around the world use lemon basil.

We're about to doing some major overhaul in our garden. I will save a spot to try lemon basil. Thanks for sharing and I look forward to trying that noodle dish. Yum!

I guess you just need to move to Hawaii! Everyone I know is growing Tulsi and lemon basil!

How different or similar is Lemon Basil to Lime Basil, which volunteers in my garden every summer and grows like a weed? I'm hoping that you say they're similar. :)I've never seen lemon basil for sale (as a plant).

Laura - Hmm. I have never tried lime basil, so I don't know.

Does anyone know?

Laura November 5, 2011 8:10 PM  

It's REALLY lime-y if that helps. :) More lime flavored than basil, although the basil is there too.

Admin November 5, 2011 9:24 PM  

Laura - I'm curious. Need to grow it to find out.

I have grown and used both lemon and lime basils. To me, they don't vary very much, but the lime basil doesn't thrive as well as the lemon in NE Oklahoma. Wikipedia says that both types have a chemical called citral in them that produces the lemony flavor and scent. This past year, I was only able to find one sickly-looking lemon basil plant, but I couldn't risk not having any to enjoy. When I went to plant it, and 5-6 other varieties of basil (couldn't find lime this year), I started noticing little plants popping up everywhere that looked strangely like lemon basil. It had volunteered everywhere, even in the middle of my bermuda grass lawn! Needless to say, I wasn't at a shortage for lemon basil. This was the first time my basil of any variety volunteered, and what was surprising was the intensity and cruelty of our previous winter and the summer in which it grew this year. Unbelievable! I would love to know what to do or how to harvest the seeds of the lemon basil plant. I suspect I have many! I love your blog. ~~Debra
