Short answer Both homemade and shop-bought pesto sauces have their advantages. If convenience is your top priority, then store-bought pesto is right for you, but if freshness is your main concern, then nothing can compete with making pesto yourself.
Long answer Just like fresh pasta vs. dried pasta, both homemade and store-bought pesto have their own distinct advantages and disadvantages. Expense, convenience, and freshness are the top deciding factors, although there are several other things to consider before deciding which route to take.
Expense Let's pretend for a second that you don't have any of the ingredients required to make a traditional basil pesto in your store cupboard. If you went to Tesco to buy them, then your shopping list would look something like this:
Obviously, you'll end up with plenty of leftover oil, cheese, salt, and pine nuts, but the trip would have cost you £15.80, compared to just £1.30 to buy a 190g jar of Tesco's own-brand basil pesto.
Ingredient quality One of the many pluses of making a sauce from scratch is that you have complete control over the quality of the ingredients that go into it. Want to crack open your favourite £30 bottle of Riviera Ligure olive oil? Go for it. If you don't much care for posh olive oil and are perfectly happy using a £1.50 bottle of vegetable oil, that's fine too.
Freshness How long ago do you think those jars of supermarket pesto were bottled? Don't be surprised if they had been sitting around in a warehouse for a month or more before hitting the shelves. That's fine because they are designed to last at least 12 months unopened, but by pure definition, jarred pesto can never be as fresh as rustling up a batch at home and eating it for dinner that evening.
Convenience Nothing can beat the convenience of twisting a lid and stirring a few dollops of pesto through some freshly cooked pasta. That said, if you're going to the effort and expense of making it at home, it's easy to whip up a double batch and freeze half of it to ensure you have some little nuggets of pesto on hand whenever you want to pep up some mashed potatoes or a weeknight Bolognese.
Predictability This can either be a pro or con, depending on your personal preference. Manufacturers of supermarket food go to great lengths to ensure that batch after batch iscompletely consistent, so that their customers know exactly what they are going to get every time. We rather like the unpredictability of not knowing exactly how our freshly made pesto is going to turn out, but it's not for everyone.
Customisability There's nothing to stop you from adding extra ingredients like chilli, lemon juice, or extra garlic to store-bought pesto, but it's never going to be as customisable as making it yourself from scratch. Making pesto at home allows you to use seasonal ingredients and also provides a free rein to make it your ideal texture. Prefer your sauces rustic and chunky or refined and creamy? You get to decide.
Furthermore, it's impossible to take an ingredient out of a sauce once it has been added, so if you have a garlic intolerance, for example, you may find you have no option other than to make pesto yourself. Making sauces at home is also ideal for anyone on a low-fat or low-calorie diet. Pine nuts, olive oil, and cheese are all high in fat and calories, so dieters may decide to reduce the quantities of those and bulk out the sauce with more healthy ingredients.
Both homemade and shop-bought pesto sauces have their advantages. If convenience is your top priority, then store-bought pesto is right for you, but if freshness is your main concern, then nothing can compete with making pesto yourself. Just like fresh pasta vs.
Unopened store-bought pesto can typically last 1-2 weeks past the printed date if kept in the refrigerator and up to 6 months in the freezer. Once opened, it should be consumed within 4 to 7 days, depending on the brand and storage conditions.
On average store-bought pesto costs less. Depending where you live, the ingredients for pesto Genovese can set you back quite a bit. Good olive oil doesn't come cheap, and neither do pine nuts. Alas, using cheap -or worse, substitute - ingredients is not an option.
In addition to preservatives and lower quality oil, other ingredients in store-bought pesto may be less than ideal. “Many store-bought brands will likely contain added salt,” says Hunnes. She adds that there may also be more health benefits to making it yourself.
The most common reason for pesto tasting bitter is that the olive oil is past its best and has started to turn rancid. If the pesto has been made in a food processor or blender, there's also the possibility that it has turned bitter from the crude, sheering action of the blades.
You might not want to douse everything you eat with pesto, but you wouldn't want to do that with any food. Variety and moderation are important. Pesto can be a healthier replacement for cream-based sauces since it's made with olive oil and nuts.
FAQ: How Long Does Homemade Pesto Last? You can store this basil pesto in a jar or sealable container, then tightly seal and refrigerate for up to 1 week or freeze for up to 2–3 months. Let it thaw at room temperature or in the refrigerator.
Once you remove the lid, however, the sauce starts to expire quickly. In fact, it's possible for store-bought pesto to go bad after just three days, and it is guaranteed that it won't be any good once it gets past the two week mark.
An adverse reaction after eating basil pesto may not be related to an allergic reaction. If you develop gas, bloating or an upset stomach you may be sensitive to some of the ingredients, such as garlic or olive oil.
The primary ingredients in pesto — basil and olive oil — are sensitive to heat. Basil can lose its vibrant color and fresh flavor when exposed to high temperatures, turning it a darker, more muted green. Olive oil can also lose some of its health benefits and can develop a bitter taste when heated excessively.
For modern makers who like the quickest method: Stick with the food processor. The pesto won't be as creamy, but if you're all about efficiency this will do the trick. For those on a budget or with small kitchens: Go for the mezzaluna or the immersion blender.
If your main goal is to cut calories and fat, go for the marinara. If, however, you'd like to add some extra nutrients via greens such as basil or kale, and nuts, such as pine nuts or walnuts, opt for the pesto every once in a while. It's a tasty alternative to marinara, and a little goes a long way.
Testersate both pestos plain and on room temperature penne. Everyone agreedthat the store-bought version was cheesier and nuttier; the homemadeversion had a stronger garlicky kick and basil brightness.
A sealed jar of pesto will typically last between four and six weeks in your pantry, with the exact "best by" date depending on the brand and type of pesto. But once you crack open a jar of the store-bought sauce, it's best to only keep it around for up to five days in the fridge.
Its scarcity, plus the fact that the plants are picked roots, soil, and all to ensure that only juvenile leaves make it into pesto, makes it extraordinarily expensive and something that only premium, artisan pesto makers can justify using.
Add a pinch of salt if the basil tastes too bitter or the pesto needs more zing. Add more Parmesan if you'd like a creamier/cheesier pesto. If desired, you can thin out the pesto with more olive oil.
The reason pesto (and guacamole) turns brown is because of a chemical reaction the cut basil has from being exposed to air. The reaction is known as oxidation. To prevent oxidation, I blanch the basil leaves for a few seconds in boiling water until they turn bright green.
What does pesto taste like? Traditional pesto is a thick, green sauce that tastes bright and herby from the basil, and salty and rich from the cheeses and pine nuts. It should be garlicky, with pleasant grassiness from good quality olive oil.
