Fruits that start with O

Let’s make things fruity by exploring this rich list of fruits that start with O, right from the delicious orange to the Osteen mango, among others, a list that is rich in vitamins, fiber and minerals.

1. O’Henry Peach

First bred from other variants in 1968 in California, the O’Henry peach is reputed for its almost completely red skin, the first peach variety to achieve this color feat. It is also a less fuzzy fruit when eating than other peaches. 

Large-sized and firm, this fruit is ready for harvest a little late into the peach season. Each fruit brings competitive nutrient portions such as vitamin C and antioxidants, for good immunity and cell protection.

2. Oillarde Noire Grape

A Provence rarity from Southern France, the Oeillade noire grape is a variety characterized by a red tinge and heavy fruition. Though now slowly sinking into ‘old fruit’ status due to increasing rarity, the fruit was once one of the richest-yielding grapes in France. In fact, its first name is a derivation of the French word ‘ouiller,’ which ascribes to paring something down due to its high yield.

The main use of the Oeillarde noire, besides raw eating, is in making grape wine. 

3. Ogallala Strawberry

True to its exotic sound, the ogallala strawberry is a fruit that bears firm berries with comely fleshy heart shapes. Not only does it have a rich, wild aroma which makes it good to eat out of hand, but it has a firm texture that is useful in fruit processing.

The ogallala is a hybrid of wild types and cultivated variants from the American Rocky Mountains region. Its date of unveiling was 1956 by the University of Nebraska and USDA.

4. Ogeechee Lime

A fruit of a rare tupelo tree from North America which also produces honey, the ogechee lime  is sour and is also called sour gum. As a plant, the fruit-bearing tree grows fast and can reach 100 feet high. It is found on the East Coast all the way to South Carolina in the US.

The ogeechee lime has a palatable acidic flavor. This dictates its main uses that include making preserves and lemonade drinks. 

5. Oil Palm

A socially and economically important fruit, the oil palm is the cooking oil-producing berry of the African oil palm, sometimes called macaw-fat. It bears a cluster of grape-like berries that have three layers:

6. Olives

Olives are the fruits of the ‘European olive’ tree that grows in the Mediterranean, which is a chief source of extra virgin cooking oil. This oil is a key ingredient in the Levant and southern European cuisine.  The fruits are nutritious as they harbor such vitamins as E and a range of antioxidants that keep the heart healthy. 

In taste, a bite at an olive brings a very bitter infusion to the tongue. Though, there are smaller oval-shaped olives that have a mildly sweet albeit salty taste. Hence, olives are cured at once in salty brine after the harvest, ready for oil extraction.

7. Opal Apple

Opal apples are hybrids of Golden Delicious and Topaz apples, under the trademarked name UEB 32642. This cross of two related varieties brings forth similar traits of its parent stocks, including a rich golden yellow skin.

11. Osteen Mango

Originating from the island of Meritt in Florida, US, the Osteen mango is a large, oblong, point-ended mango. The fruit is ready for picking around July through September in its native southern State.

Oca is a world apart from a potato: 

  • It is edible, skin and all, raw or cooked.

18. Okra

Popular in gardening culture as ladies fingers, okra is a mallow that produces edible pointed corms or green seed pods. Though there is a difference of opinion as to its origin, there is however consensus that it may have come from West Africa, Ethiopia or South Asia.

19. Orach

Orach is an edible weed that is sometimes called French spinach despite the fact that it preceded spinach as a wild vegetable. The mountain spinach, as it is alternatively called, is related to amaranth and makes a competitive replacement to spinach.

20. Orange Acorn Squash

Orange acorn squash is a winter squash with a ridged green rind that turns to orange when ripe. The flesh is usually yellow and tender. Color is one of the tell-tale signs of the palatable nature of this gourd: when it is orange-skinned, it is usually just to go bad and it is best to consume it before it rots.

On the dinner table, the orange acorn squash will usually taste mildly sweet with a nutty nuance. You can cook it as a baked good, a roast or even a sautee. 

21. Oxheart

Oxheart is not what you think: it is not meat but a type of tomato that is curiously shaped like a rounded, ribbed heart. This cultivar is firm and red-skinned with a striking similarity to beefsteak tomatoes. The color can however differ greatly from one place to another: sometimes yellow, other times green and even purple.  

Oxhearts have a very salivating aroma and a taste that is a mixture of the lively sweet and the playfully acidic. 

Dairy and Eggs that start with O

The surprising element about this list of dairy and eggs that start with O is that, with the exception of one, they are simple words that even a child can pronounce!

22. Oma

Oma is a washed-rind pancake-like cheese that is obtained from whole milk of cows of the Jersey Breed or a related breed. This branded cheese comes from the Van Trapp farm where it is creamed and ripened.

The secret for its popularity is the careful blend of sweet and sour aromas through the embellishing ingredient of roasted nuts.  In taste, you can therefore expect a bittersweet aroma with some highlights of rich cream.  

23.  Om

Om is a short form for cheese omelet or omelet cheese.  It is made just like a normal egg-based omelet only that it contains a good measure of cheese and other ingredients. It can contain turmeric and bell peppers, which makes it more of a dish than a true cheese.

In cuisine, octopuses make good grills: they are soft, meat, and somewhat chewy in texture and exude a slightly sweet taste with a welcoming marine waft on the nose.

28. Offal

A bite at a grilled orange roughy will bring you a very delicate, sweet flavor for a deep sea creature, with not much of a fishy aroma. You will find the texture flaky and firm. 

33. Oxtails

Oxtail refers to just what you are thinking now: that cut or chop of a bull’s whole tail. Though it originally only indicated the tail of an ox, nowadays the term has a qualified meaning to also include cows. 

Weighing 3.5 kilos on average, the oxtail is a savory meat akin in taste to beef. Besides, it has high fat content, albeit most of it saturated.  With protein levels of 16 percent of the daily value, you are, however, in good health territory when eating oxtail.

48. Ohitashi

Ohitashi or Spinach ohitashi is a leafy greens-based dish, whereby veggies are steeped into a sauce based on the dashi soup-making culture of Japan.

Oat milk is one of those healthy whole grain extracts that you should have for a heady bone-strengthening breakfast. It is made from whole oats which are dipped in water to release the creamy milky stuff. Oat milk has a slight flavor like that of oatmeal. You can have it from a shop, only that this time it will be flavored with chocolate or vanilla nuances, and even sweetened a bit. 

70. Ogi

Ogi is a pap or porridge which is better known as a key ingredient for the common Nigerian drink, Adoyo. To make adoyo, ogi is mixed with boiling water containing decanted slices of pineapple, lemongrass and sometimes orange. It is taken straight from the hose without adding any artificial coloring.  Thus, it is a welcoming healthy morning drink.
