Lemon curd, a tangy and sweet spread made from lemons, sugar, eggs, and butter, is a popular topping for toast, scones, and cakes. When stored in a jar, lemon curd can be a convenient and delicious addition to various recipes. However, like any food product, lemon curd in a jar can go bad if not stored properly or if it has exceeded its shelf life. In this article, we will explore the shelf life of lemon curd in a jar, factors that affect its spoilage, and provide tips on how to store it to maintain its quality.
Understanding the Shelf Life of Lemon Curd in a Jar
The shelf life of lemon curd in a jar depends on several factors, including the recipe, storage conditions, and packaging. Generally, homemade lemon curd can last for several weeks to a few months when stored in the fridge, while store-bought lemon curd can have a longer shelf life due to added preservatives.
Homemade Lemon Curd Shelf Life
Homemade lemon curd typically has a shorter shelf life compared to store-bought versions. When stored in the fridge, homemade lemon curd can last for:
- 2-3 weeks at 40°F (4°C) or below
- 1-2 weeks at 45°F (7°C) or below
It’s essential to note that homemade lemon curd can be frozen to extend its shelf life. When frozen, lemon curd can last for up to 6-8 months.
Store-Bought Lemon Curd Shelf Life
Store-bought lemon curd, on the other hand, can have a longer shelf life due to added preservatives. The shelf life of store-bought lemon curd can vary depending on the brand and storage conditions. Generally, unopened store-bought lemon curd can last for:
- 6-12 months at room temperature (68°F-72°F or 20°C-22°C)
- 12-18 months in the fridge (40°F or 4°C or below)
Once opened, store-bought lemon curd can last for:
- 2-3 weeks in the fridge (40°F or 4°C or below)
Factors That Affect the Spoilage of Lemon Curd in a Jar
Several factors can affect the spoilage of lemon curd in a jar, including:
Storage Conditions
Storage conditions play a significant role in the shelf life of lemon curd in a jar. Lemon curd should be stored in a cool, dry place, away from direct sunlight and heat sources. The ideal storage temperature for lemon curd is between 40°F (4°C) and 45°F (7°C).
Packaging
The packaging of lemon curd can also affect its shelf life. Lemon curd stored in a jar with a tight-fitting lid can last longer than those stored in jars with loose lids. Additionally, jars with a wide mouth can allow more air to enter, which can cause the lemon curd to spoil faster.

The recipe used to make the lemon curd can also affect its shelf life. Lemon curd made with a high sugar content can last longer than those made with low sugar content. Additionally, lemon curd made with eggs can be more prone to spoilage than those made without eggs.
Signs of Spoilage
It’s essential to check lemon curd in a jar regularly for signs of spoilage. Some common signs of spoilage include:
- Off smell or odor
- Slime or mold on the surface
- Slimy or soft texture
- Rancid or sour taste
- Color change (e.g., from bright yellow to green or gray)
If you notice any of these signs, it’s best to err on the side of caution and discard the lemon curd.

What is the typical shelf life of lemon curd in a jar?
The typical shelf life of lemon curd in a jar depends on various factors, including the storage conditions, acidity level, and preservatives used. Generally, homemade lemon curd can last for 6-12 months in the fridge, while store-bought lemon curd can last for up to 18 months. However, it’s essential to check the expiration date or “best by” date on the jar label to determine the manufacturer’s recommended shelf life.
It’s also important to note that lemon curd is a high-acid food, which means it can be more resistant to spoilage. However, this doesn’t mean it’s invincible. Over time, the acidity level may decrease, allowing bacteria and mold to grow. Therefore, it’s crucial to store lemon curd in a clean, airtight jar and keep it refrigerated at a consistent temperature below 40°F (4°C).
How can I tell if lemon curd in a jar has gone bad?
To determine if lemon curd in a jar has gone bad, look for visible signs of spoilage, such as mold, yeast, or an off smell. Check the jar for any signs of leakage, rust, or corrosion, as these can compromise the integrity of the curd. If the curd has separated or developed an unusual texture, it may be a sign that it’s no longer good.
If you’re still unsure, perform a taste test. If the lemon curd tastes sour, bitter, or unpleasantly sharp, it’s likely gone bad. Additionally, if you notice any slimy or grainy texture, it’s best to err on the side of caution and discard the curd. Remember, when in doubt, it’s always better to be safe than sorry, especially when it comes to food safety.
Can I freeze lemon curd in a jar to extend its shelf life?
Yes, you can freeze lemon curd in a jar to extend its shelf life. Freezing is an excellent way to preserve lemon curd, as it prevents the growth of bacteria and mold. When freezing, make sure to use a clean, airtight jar and leave about 1/2 inch (1 cm) of headspace to allow for expansion. Label the jar with the date and contents, and store it in the freezer at 0°F (-18°C) or below.
Frozen lemon curd can last for up to 2 years. When you’re ready to use it, simply thaw the curd in the fridge or at room temperature. Note that freezing may affect the texture of the curd, making it slightly more watery or separated. However, this shouldn’t affect its flavor or safety.
What is the best way to store lemon curd in a jar to maintain its quality?
To maintain the quality of lemon curd in a jar, store it in the refrigerator at a consistent temperature below 40°F (4°C). Keep the jar away from direct sunlight, heat sources, and moisture. Use a clean, airtight jar with a tight-fitting lid to prevent contamination and spoilage.
It’s also essential to keep the jar upright and avoid exposing the curd to air, as this can cause it to oxidize and lose its flavor. If you won’t be using the lemon curd for an extended period, consider freezing it to extend its shelf life. Always check the jar for any signs of spoilage before consuming the curd.
Can I make my own lemon curd at home, and how long will it last?
Yes, you can make your own lemon curd at home using a simple recipe that includes lemons, sugar, eggs, and butter. Homemade lemon curd typically lasts for 6-12 months in the fridge, depending on the storage conditions and acidity level. To extend its shelf life, consider adding a preservative like lemon juice or citric acid.
When making lemon curd at home, it’s essential to follow proper food safety guidelines to prevent spoilage and contamination. Use fresh, high-quality ingredients, and cook the curd to an internal temperature of at least 160°F (71°C) to kill off any bacteria. Store the curd in a clean, airtight jar and keep it refrigerated at a consistent temperature below 40°F (4°C).
Is it safe to eat lemon curd that’s past its expiration date?
It’s generally not recommended to eat lemon curd that’s past its expiration date, as it may have spoiled or developed off-flavors. While lemon curd is a high-acid food that’s more resistant to spoilage, it’s still possible for bacteria and mold to grow over time.
If you’re unsure whether the lemon curd is still safe to eat, check for visible signs of spoilage, such as mold, yeast, or an off smell. If the curd looks, smells, and tastes fine, it’s likely still safe to eat. However, if you notice any unusual texture, flavor, or aroma, it’s best to err on the side of caution and discard the curd.
Can I use lemon curd that’s been stored at room temperature for an extended period?
It’s not recommended to use lemon curd that’s been stored at room temperature for an extended period, as it may have spoiled or developed off-flavors. Lemon curd is a high-acid food that’s more resistant to spoilage, but it’s still possible for bacteria and mold to grow when stored at room temperature.
If you’ve stored lemon curd at room temperature for an extended period, check for visible signs of spoilage, such as mold, yeast, or an off smell.
