Fennel Immune Booster | Perchance to Cook,

This fennel based juice is one of my all time juices. I discovered a similar juice at a breakfast place called Satsuma in New Orleans and knew that I had to recreate something similar at home.

So, I came up with my own version of it and have been drinking it ever since. It has a hint of anise flavor (thanks to the fennel), with lots of citrus tastes and an overall refreshingly and light taste.

If you are wondering what fennel juice tastes like, don’t worry!

It has a light anise flavor, but it doesn’t taste like strong licorice.

Also, don’t be afraid if you drink it in 30 seconds… it just disappears so quickly! Especially with a straw. Which is great considering how many fruits/veggies are inside!

How to make fennel juice

If you’ve wondered how to juice fennel bulb, look no further!

It is simple, cut your fennel bulb into pieces that fit your individual juicer. I personally use a waring pro juicer.

And then you put the fresh raw fennel into your juicer and collect the juice.

This is all you need to know to juice fennel bulb.

How to make this Immune Booster Fennel Juice

First step– wash all your fruit and vegetables

Second step– cut your fruits and veggies to fit into your juicer

Note: the peel of the citrus needs to be removed so your juice isn’t butter

Third step– juice!

After all of the juice has been extracted from your juice extractor, then mix the juice together with a spoon, then pour and serve.

Variations to this juice

You can add berries or carrots to this juice to change up the flavor or add more nutrients.

I personally love adding carrots because I find carrots to be powerhouses of vitamins and minerals.

More information about juicing:

I got into juicing after reading the Juiceman’s Power of Juicing and that transformed my life.

It’s my favorite juicing book because the recipes are realistic and the information on fruit/veggie combinations is important (the combinations do matter).

One thing that I learned from the book is that after cutting open a fruit or vegetable and juicing them, the nutrients of the fruits and vegetables instantly begin to lose their power so you shouldn’t wait more than 10 minutes to drink it.

I have tried pretty much all of his recipes and spent a good year being really adamant about having a different juice every time that I made it. Fast-forward to now, and I stick to my five favorite recipes.

I juice 4-5 times a week and alternate between those five. I sometimes change things up and throw in extra berries or carrots lying around. For this Fennel Immune Booster, for instance, I add carrots to it about every other time that I make it.
