An offshoot of my hunt for vodka infusion recipes has been the discovery of non-alcoholic cordial. Cordials are syrups, usually fruit-flavored, that are meant to be mixed with chilled sparkling water to make sodas. I did not know this. I mean, when I made an all-purpose strawberry syrup I added it to sparkling water, and I buy sparkling water+Torani syrup sodas from my local cafe, but I didn't know there were entire nations inventing syrup recipes specifically for fizzy water. Wow. I have been missing out, man. Maybe I never noticed because to me "cordial" means boozy, and "syrup" is an all-purpose word for sugary liquidy stuff. I used "syrup" and "cordial" interchangeably in the post because I haven't settled on one or the other. Neither sounds exactly right to me.
OK! Cordial time!
Strawberry-Cardamom Cordial

I know I've posted a million pictures of bottles of pink stuff that all look the same. I swear it is not the same bottle of stuff in every picture. Even though it really looks that way.
This is just great. Tastes great, smells great, looks beautiful. I'm crazy about it. The only downside is the sugar. I drink flavored sparkling water all the time, and usually buy the zero calorie kind, which this is not. However, adding two tablespoons to a glass of water doesn't seem like that much, and the drink it makes is very lightly sweet. I suggest measuring the two tablespoons, though--it's easy to add a lot more than that, and it tastes really good (not that I would know). Also, I didn't know how to bruise a cardamom pod, so I looked it up, and read to nick it with a knife, so the flavor, but not the seeds, would come out during cooking. Well, I am a big cardamom fan, and the flavor wasn't strong enough to suit me, so after tasting the mixture while it was cooking, I crushed the pods. A couple seeds did make it through the strainer, but I don't care.
I liked the Strawberry-Cardamom cordial (recipe is in the link list at the end of the post) so much that I wanted to find lots more cordial recipes. This was kind of aggravating, because there is no way to differentiate between syrup meant for pancakes and soda syrup, except by looking at the amount of sugar and water in the recipe, and also no way to know if it's an alcoholic cordial or not except, again, by looking at the recipe. I got the best results from adding "sparkling water" to the search terms. In other words, "peach cordial sparkling water", and if that yielded nothing, "peach syrup sparkling water".
The results of the hunt are in the link list below. Unless the recipe says otherwise, these syrups keep, refrigerated, for about a week.
Some call for citric or tartaric acid, preservatives which improve their longevity and enhance flavor (or so I read). They can be omitted, but then the cordial should be used within a week. I don't have any experience with these acids, so I don't know how much they affect flavor.
Caster sugar is superfine (not powdered or confectioner's) sugar.
You can strain through coffee filters or cheesecloth if you don't have the muslin some of the recipes mention. Cheesecloth might be the same thing as muslin anyway.
I included flavors I'm not familiar with if the recipe sounded good--I wouldn't know a rosella from a tube sock, but maybe you are not as challenged. I also have no idea where I would get fresh elderflowers, so for locals, there is an elderflower sparkling water by the brand Bottle Green at Dean & DeLuca, and when I was buying it, the cashier told me there is an elderflower cordial available too (she called it "concentrate"). I forgot to look for the cordial, but I will next time I am there. I liked the elderflower sparkling water.
9/11/11: I am going to update this post every now and then after I make some of these to give reviews. I have made Blackberry-Orange and Strawberry-Ginger-Mint. Both were very good. Blackberry-Orange was very flavorful and sweetened with agave nectar, so not too sweet, but sweet enough. I think I might have mentioned it in another post. Strawberry-Ginger-Mint was great! Really interesting flavor--it also has balsamic vinegar as an ingredient. The recipe said it would keep indefinitely, and it makes a lot, so it took me about a month to use it up and it does keep, it was totally fine.
9/22: Made Blood Plum, but I used black plums and vanilla extract instead of a vanilla bean. Meh. It tastes great by itself and would make a fantastic ice cream soda, but not so hot in sparkling water. The plum flavor doesn't stand up to dilution, so all you taste is vanilla.
11/8: Found the Bottle Green elderflower cordial! It's really good! For New Yorkers, I found it at the Madison Dean&DeLuca. I have never seen it at the Soho one.

11/14 Found a clementine recipe which I just made and added to the list. Fast, easy, and good.
11/20 Made Blackberry-Verbena, which I just added to the list. I was put off by this recipe's supposed yield, 4 servings, but I had a blackberry surplus, so I decided to try it. It filled a bottle like the one in the top picture with about half a cup to spare. I guess it depends on how much you use, but they suggest one part cordial to three parts soda water, and following that ratio, it makes a lot more than four servings, so I don't know where they came up with that number. I was glad though! I used pineapple sage instead of lemon verbena. It turned out really well. Pressing the pureed blackberries through a sieve to extract the juice was a purple pain, but the flavor is very nice.
2/28 Made Vanilla Bean. It's the best vanilla I have made so far, but I wish it was a little more concentrated. I'm drinking a vanilla soda right now though, so I don't know what I'm complaining about. Also discovered a whole shelf of syrups at Dean&Deluca Soho, somehow I completely missed them before. I bought lingonberry, to recreate the Ikea cafeteria experience, and almost passed out when they rang it up. I think it was 16 dollars OMFG that is not an Ikea price. This is a good reason to make your own. I saw some other syrups (also expensive, but not quite as crazy) at the Bedford Cheese Shop in Williamsburg, but haven't tried them yet.
7/30 I have made Berry, Raspberry-Rosewater, and Blueberry. All were good. Berry is a good one to make to use up berries that are getting old. Raspberry-Rosewater is on the thick side, and the rosewater doesn't come through as much as I'd like, but it's still nice. Blueberry is the real star. You make it, and then leave in the fridge for 4+ days to infuse before straining, and damn it is good. The best yet. It calls for 40g of tartaric or citric acid, which totally confused me because my citric acid is a tiny little bottle of liquid, but it's an optional ingredient, so I just tossed in a few drops.

They suggest mixing this with ginger beer and Pimm's, not water, but it sounded so good I couldn't leave it out.

Rosella (Australian Hibiscus)
You have to scroll down to find it.
Rosemary, Red Currant, and Orange
Star Anise
This is a page of cocktail recipes and you have to scroll down to "Antoine Peychaud" to find the Star Anise Syrup recipe. The recipe isn't a true cordial, it's a cocktail mixer, but I looked for an anise cordial recipe and this is the closest I found.
Strawberry
Strawberry-Cardamom
Strawberry, Ginger, and Mint
Strawberry-Rhubarb
Strawberry-Rose Petal
I pasted this one rather than linking because it is in fucking annoying PDF.
If you’re lucky (and green fingered) enough to grow old-fashioned scented roses, then spare a handful or two of the petals to be added to this cordial. Store the cordial in the fridge and serve diluted to taste with sparkling mineral or soda water and plenty of ice. Or pour a generous glug over vanilla ice cream and add a handful of sliced summer berries for a scrumptious ice cream sundae.
MAKES ABOUT 500ml
300g caster sugar
juice and zest of 1 unwaxed lemon
500g ripe hulled strawberries, quartered
2 handfuls of fragrant,unsprayed rose petals, washed
1 teaspoon citric acid
Put the sugar into a medium-sized pan and add 300ml of cold water.
Using a vegetable peeler, pare the zest from the lemon in strips and add
to the pan along with the squeezed lemon juice. Set the pan over a low
to medium heat, stirring occasionally to dissolve the sugar, then bring to
the boil and simmer for 2 minutes.
Remove the pan from the heat and add the strawberries, rose petals and
citric acid. Gently crush the berries in the pan with the back of a spoon.
Leave the fruit and petals to steep in the syrup for about 4 hours.
Strain the cordial through a fine sieve or muslin, then pour into sterilised
bottles, seal and label. Store in the fridge until ready to serve.
Strawberry-Vanilla
Vanilla (Bean)
Vanilla (Extract)
This is a recipe for vanilla cream soda which includes a vanilla syrup recipe.
