It's an unwritten rule that every time you visit your sister, you take home more than you showed up with.

This time was no different.

Share with thy neighbour and all that.

During one visit, while we were out checking out her garden, pointing at things, nodding and saying garden-y words, I happened to notice that one plant was doing exceptionally well.

I mean, like real good. It was growing at a rate that was overtaking her sidewalk. The leaves were getting to be the size of beach towels!

My sister, Kate, inherited my mom's bread making genes, her skinny jeans, and also her green thumb.

I helpfully, and maybe a little selfishly, suggested we should harvest some.

You know, seeing as it's a rhubarb patch the size that can make foodies drool, freezers short on space, and gardeners string together a line of curse words that would make a sailor blush!

This rhubarb simple syrup is dedicated to the plant you can't kill and my sister.

Wait.... That sounds kinda twisted.

This rhubarb recipe is dedicated to the vegetable that wants to be a fruit.

HERE'S WHAT YOU NEED TO KNOW ABOUT THIS RHUBARB SYRUP RECIPE:

RED vs green stalks - I did some searching, it turns out that red stalks are not sweeter than green stalks. I learned something new today!

SIMPLE syrup is versatile! I've used this one to make soda, drizzled on pancakes or waffles, a glug in smoothies, and stirred into ice cream.

I never understood why they call mixing equal parts of water and sweetener with fruit - there's nothing simple about the flavour!

THE colour is true in these photos. Rhubarb is so vibrant and fun. I just love cooking with it!

CINNAMON is optional, but it adds a little something to this rhubarb syrup. Try with or without.

I developed this recipe without any refined sugar, but if you like, you can sub in granulated white sugar for the honey/maple syrup.

2019 brought an update to this rhubarb syrup recipe - I've adapted it to the Instant Pot! You can now go forth and make Instant Pot simple syrups.

YOU can use either a fine-mesh sieve or a nut milk bag to separate the pulp from the juice in this recipe. I've used both, and the nut milk bag is faster, but messier, while the strainer needs a bit more babysitting and time.

THIS rhubarb honey syrup is one of my favourite rhubarb recipes!

Can same amount of regular white sugar be substituted for the honey in this recipe for Rhubarb Simple Syrup. TIA for your attention to this question. Denise A aka: [email protected]

Hi Denise, you bet! Feel free to use honey instead of granulated sugar in this recipe, the reason I use white sugar is that it's got a very mild flavor and you may find that honey imparts a distinct flavor, either way it should be delicious!

This is so simple in the instant pot. I skipped leaving 6 inch pieces on the rack and cut 1 inch pieces. When it was cool I drained it in my sieve. I'm going to use the mush part as a schmir for toast and pancakes. The Cinnamon makes it delicious.

Great idea to use the pulp as a spread!
